A major fire incident in a Swedish underground mine made the personnel from the mining company and the rescue service realize their limited preparedness. It was the beginning of a collaboration project that included the development of a new exercise model for a more effective joint rescue operation practice. The aim of this study was to explore the collaborative learning process of exercise organizers from the rescue service, mining companies, the emergency medical service, a training company, and academia. The analysis was performed through the application of the theory cycle of expansive learning to the material consisting of documents from 16 collaboration meetings and 11 full-scale exercises. The learning process started by the participants questioning the present practice of the rescue operation and analyzing it by creating a flow chart. An essential part of the process was to model new tools in order to increase the potential for collaboration. The tools were examined and tested during collaboration meetings and implemented during full-scale exercises. The exercise organizers reflected that the process led to organizational development and a better understanding of the other organizations’ perspectives. Consequently, a tentative model for developing the learning process of exercise organizers was developed.

Introduction:Major injury incidents in underground metalliferous and mineral mines are rare, but if, e.g., a major fire would occur, it is the emergency medical service (EMS) together with the mining company and rescue service who perform the rescue operation. Therefore it is important to develop safe and efficient rescue operation procedures for all the organizations involved, especially the EMS personnel.Aim:To examine EMS personnel’s perceptions and experiences regarding underground mining incidents.Method:Individual interviews were performed with 13 Swedish EMS personnel. The interviews were transcribed verbatim and analyzed with qualitative content analysis.Results:The theme “providing the same care in a difficult environment” emerged. Depending on the type of incident, the EMS personnel considered if the injured mining workers could be cared for either outside or in the mine in order to access and care for the injured mining workers as quickly as possible. The EMS personnel mentioned that it was difficult to make the decision if they should enter the mine or not due to the uncertainty of their safety. They also considered that it could be harder to accomplish the same level of care as in other incidents due to the difficult environment. In some instances, they cannot drive their ambulance vehicles into the mine, so they have to prioritize which equipment to bring as well as consider how to transport the patients.Discussion:The results identify some of the difficulties the EMS find challenging. Therefore the results could be used in finding solutions and making the EMS prepared for an effective and timely response for injured in underground mines.

Talnakh and Oktyabrsky ore fields are estimated as rockburst-hazardous starting from the depth of 700 m downward according to safety rules. This means that mining is only permitted within certain protected zones. At the present times, such protected zones are generated in underground mines by means of the large-diameter destressing drilling. Despite proved efficiency, the high cost and large amount of the destressing drilling are the grave faults of this approach. Aiming to save drilling cost, it is proposed to make rock mass rockburst-unhazardous using destress blasting. This article gives a brief description of the destress blasting mechanism. This method has been effectively used in relaxation of pillars from stresses before extraction of the reserves from the pillars both in Russia and abroad. In Oktyabrsky Mine stress relaxation of pillars was implemented by slotting, and the drilling and blasting data were available. This study proposes to destress rock masses by means of directional destress fracturing in horizontal plane through blasting of decked charges of special design. The initial parameters for destress blasting using holes with diameters of 76 and 130 mm are determined. The charge design aimed to ensure a zone of fractures in the horizontal plane, at minimized vertical fracturing is described. This information can be used in planning of full-scale tests to refine parameters and application ranges of the method. For the full-scale tests, it is suggested to undertake destress blasting at different blast patterns on different test sites, and to compare the results with the current destressing method (destressing drilling). Efficiency can be proved using geomechanical and geophysical methods. The authors appreciate participation of V. P. Marysyuk and T. P. Darbinyan from NorNickel’s Polar Division in this study.

PurposeThis paper presented the learning process of a group of primary mathematics teachers who participated in two iterations of lesson design, enactment and reflection in a Chinese Lesson Study.Design/methodology/approachAn expansive learning theory was employed to examine the teachers’ learning process in lesson study (LS) on representing fractions on a number line. The evolution of a germ cell was utilized to feature the transformation of the object of activity from abstract to concrete through resolving contradictions among LS members. The videos of lesson planning, research lessons (RLs) and debriefing meetings were collected and analyzed to reveal the expansive learning process.FindingsThe analysis showed that the teachers expanded their learning through transforming the object from diffuse to concrete and expanded through consciously articulating the germ cell. The outcomes of object-oriented activity include improving the enacted lesson which promoted students’ conceptual understanding.Originality/valueThis study made a unique contribution to understanding the learning process of teachers in Chinese LS from the perspective of expansive learning.

This study (conducted as PhD research at Rhodes University, South Africa) describes a formative interventionist research project conducted to explore factors inhibiting improved wetland management within a corporate plantation forestry context and determine if, and how, expansive social learning processes could strengthen organizational learning and development to overcome these factors. A series of formative interventionist workshops and feedback meetings took place over three years; developing new knowledge amongst staff of Company X, and improved wetland management practices. Through the expansive learning process, the tensions and contradictions that emerged became generative, supporting expansive learning that was reflectively engaged with throughout the research period. The study was== supported by an epistemological framework of cultural historical activity theory and expansive learning. Realist social theory, emerging from critical realism, with its methodological compliment the morphogenetic framework gave the research the depth of detail required to explain how the expansive learning, organizational social change, and boundary crossings that are necessary for assembling the collective were taking place. This provided ontological depth to the research. The research found that expansive learning processes, which are also social learning processes (hence we use the term ‘expansive social learning’, supported organizational learning and development for improved wetland management. Five types of changes emerged from the research: (1) Changes in structure, (2) changes in practice, (3) changes in approach, (4) changes in discourse, and (5) changes in knowledge, values, and thinking. The study was able to explain how these changes occurred via the interaction of structural emergent properties and powers; cultural emergent properties and powers; and personal emergent properties and powers of agents. It was concluded that expansive learning could provide an environmental education platform to proactively work with the sociological potential of morphogenesis to bring about future change via an open-ended participatory and reflexive expansive learning process.

Purpose The purpose of this paper is to examine emergency medical service (EMS) personnel’s perceptions and experiences of managing underground mining injury incidents. Design/methodology/approach In total, 13 EMS personnel were interviewed according to a semi-structured interview guide. The interviews were transcribed verbatim and analyzed using qualitative content analysis. Findings An underground mining environment was described as unfamiliar and unsafe and, with no guidelines for operational actions in an extreme environment, such as underground mines, the EMS personnel were uncertain of their role. They therefore became passive and relied on the rescue service and mining company during a major incident. However, the medical care was not considered to be different from any other prehospital care, although a mining environment would make the situation more difficult and it would take longer for the mine workers to be placed under definitive care. Originality/value This study complements earlier studies by examining the EMS personnel’s perceptions and experiences of major incidents.

ALROSA performs blasting operations mainly using explosives manufactured on the spot. Considering modern trends of using local manufacture explosives, Company’s experience of application of emulsion explosives, as well as prompt introduction of technological innovations, novel process solutions are utilized in manufacture and use of emulsion explosives. To this effect, Udachny Mining and Processing Plant constructed and commissioned a plant to manufacture non-explosive components for emulsion explosives within the Plant’s infrastructure area. Emulsion explosives enable blasting in open pit and underground mines which are assumed hazardous in terms of oil and gas shows. Within the framework of technical upgrading at MMLT-500-PR Plant, the investment project on construction and commissioning of a modular production line to manufacture packaged emulsion explosives has been implemented. The field trials of NPGM grade emulsion explosive has proved the economic and production efficiency of blasting using this explosive in open pit and underground mining. This article presents the results of testing and application of NPGM emulsion explosive during blasting in open pit and underground mines of ALROSA. The outcomes of pilot explosions using this type explosive as the main borehole and chain charges, as well as intermediate detonators in full-scale conditions of an underground mine and in an open pit are described. The proposed technology features higher operational efficiency and is applicable in various geotechnical conditions of mineral mining.

Fire and Rescue Service is an agency to handles fire problems, i.e building fires. Fire and Rescue Service of Pekanbaru is an agency to handles fire problems in Pekanbaru where the service receives information about a fire incident quickly and responsively. Fire incidents can occur anywhere, in any location, both easy or difficult access, but the Firfighter Team must be prepared in every conditions. The problem is that not all fire incidents occur in easy access places by firefighters. The incidents sometimes occur in difficult places to reach and unknown location, firefighter have to use maps to find the location. It will be wasting time to find unknown location and took a long time to arrive. The solution of this problem is to build an android-based application that can be used as a fire incident report, which is connected in one application, so residents can report through an application automatically provides the coordinates of incident. The application of Ant Colony Optimization method in finding fire locations makes it easier to hasten in searching fire locations and can be used by the public in reporting fires to Fire and Rescue Service of Pekanbaru to be processed quickly.

Introduction:Major injury incidents in confined settings such as tunnels and underground mineral- and metalliferous mines are rare, but when they do happen, the consequences may be severe with potential for many injured. The incident site is underground and it is difficult for the rescue and emergency medical service to get an overview and reach the injured. Therefore, it is important for the emergency medical service, rescue service, and the company responsible for the underground environment to have a good collaboration.Aim:To develop best practices of conducting rescue response from a disaster medicine perspective in tunnels and underground mines through increased education.Method:Within an EU-program, the university collaborates with stakeholders such as rescue service, emergency medical service, and two mining companies. Within this project, an explorative case study with participatory research is conducted. This is managed with the help of representatives of the stakeholders, workshops, and through planning for and conducting observations of table-top and full-scale exercises.Results:At the first workshop the stakeholders built a timeline presenting their activities from a major incident occurring in an underground mine until the last injured was transported to the hospital. Thereafter, several workshops were conducted to find improvements that could be made regarding collaboration between the organizations. Table-top and full-scale exercises have also revealed further challenges. Within the project, prototypes are being developed and will be presented during the conference.Discussion:This project involves stakeholders in the research process, and they, therefore, have a direct impact on the development of best practices of rescue in major underground incidents.
