Abstract The main subject of this paper focuses on scientific and research activities conducted in the Institute of Mining Engineering and Safety of the VŠB-Technical University of Ostrava. Cooperation between the VŠB-Technical University of Ostrava and OKD A.S., the only representative of coal mining in the Ostrava-Karviná coal basin, has recently begun to develop again. This paper describes an example discussed in a certain study, which has been undertaken for the Paskov mine, OKD a.s., dealing specifically with the evolution of microclimate parameters in mines that depend on the progress of mining activity at deeper levels over a period of several years. To this end, a special program, aimed at determination of the necessary refrigerating capacity, was established at the VŠB-Technical University of Ostrava.

This paper deals with two relevant and interrelated directions of coal mining development. Firstly, the resource-saving complete extraction of reserves, and secondly, the intensification of mining activity through mining operations conducted on several seams. The objective of overworking of mine workings with a real representation of mining-and-geological and mining-engineering conditions has been formulated. Five peculiarities of the geomechanical models construction for overworking of mine works have been revealed and substantiated. The technology for performing a series of computational experiments is proposed. The task of the protecting pillar influence, which is located in overlying coal seam, on the state of mine working placed in the underlying coal seam has been solved. An optimal scheme for its maintenance is proposed.

Research Activities

The ‘West Review’ argues that the determination of tertiary sector education program offerings should be decentralised by basing funding on student preferences. Research activities should be centrally prioritised with access to training being also dependent on such preferences. These views are questionable. Informational asymmetries imply that student sovereignty is a poor basis for designing programs and allocating research funds. Central prioritising cannot provide the benefits achievable in liberal structures which promote diversity. The Review's endorsement of centralised university management will realise measured cost savings but at the expense of quality.

Coal Mining Area

Presents information about geology, lithostratigraphy and the composition of the coal found in the stage of exploration in the area of contract FJS-112 of mine NATAGAYMAS, municipality of El Espino-Boyacá, Colombia. There was recopilation and bibliographical review for geological – mining studies for coal mining area of the municipality of El Espino, and preliminary recognition of the zone of study visits, the collection and review of geological studies - locating outcrops of coal of the Guaduas formation (Ktg). Regional and local information was collected in the field. Sampling of the robes of interest was conducted according to the norms established by ECOCARBON Ltda. Geological mapping with its geological profiles in which the trace of the robes of coal found was developed. Calculate of the resources was according to the ECOCARBON norms
