Tailings Reservoir

The tailings dam is a very important component part in mine production facilities. Meanwhile, it is a potential major risk source with high potential energy. Through collecting many accidents of the tailings dam, it is showed that accident type of the tailings dam mainly is dam-break, damage of drainage system, leakage of tailings, etc. On the basis of this analysis, the main causes of dam-break are slope instability, breaking construction rule, unusual rainfall, etc. The automatic safety monitoring and management system of the tailings reservoir (ASMMS) is a powerful measure for mine safety production. The basic frame of the ASMMS is proposed. The main contents and key problems of the ASMMS are also analyzed. It can provide a strong theoretical and technical basis for the safety and management of the tailings dam.

Tailings Reservoir

An assessment approach in regard to tailings dam break would be analyzed and established in aspects of life, property and environment & resources loss in the essay. Tailings bam break hits local social economy varying with region as a result of particular and specialized space diversity. With the simple and practicable approach, it is quite reasonable to accomplish quantitative assessment of risk as well as review controlling priority to potential risk arising from tailings reservoir.

Safety Monitoring System

Coal mine is important and basic industries in the country, and it is very important to establish a sound, reliable coal mine safety monitoring system for the safety production of coal mine. The demand analysis was made for the development of coal mine safety monitoring system. It contains to build up the layout model of the standard coal mine underground production environment and set all kinds of underground transducers especially methane transducer. On this basis, the general design scheme of coal mine safety monitoring system was determined. Demand analysis and scheme design provided for coal mine safety monitoring system can meet the needs of practical application and establish the foundation for the subsequent system development.

Alerting System

Safety is the most vital part of any type of industry. In the mining industry safety and security is a fundamental aspect of all. To avoid any types of accidents mining industry follows some basic precautions. Still accidents take place in underground mines due to rise in temperature, increased water level, and methane gas leakage. Here we provide safety to worker. When worker in danger he can press panic switch inform security. To enhance safety in underground mines, a reliable communication system must be established between workers in underground mines and fixed ground mine system. The communication network must not be interrupted at any moment and at any condition. A cost effective zigbee based wireless mine supervising system with early-warning intelligence is proposed in this project. Worker status can be monitor over IOT.

Abstract. The Huafan University campus is located in the Ta-lun Shan area in northern Taiwan, which is characterized by a dip slope covered by colluvium soil of various depths. For slope disaster prevention, a monitoring system was constructed that consisted of inclinometers, tiltmeters, crack gages, groundwater level observation wells, settlement and displacement observation marks, rebar strain gages, concrete strain gages, and rain gages. The monitoring data derived from hundreds of settlement and displacement observation marks were analyzed and compared with the displacement recorded by inclinometers. The analysis results revealed that the maximum settlement and displacement were concentrated on the areas around the Hui-Tsui, Zhi-An, and Wu-Ming buildings and coincided with periods of heavy rainfall. The computer program STABL was applied for slope stability analysis and modeling of slope failure. For prevention of slope instability, a drainage system and tieback anchors with additional stability measures were proposed to discharge excess groundwater following rainfall. Finally, threshold value curves of rainfall based on slope displacement were proposed. The curves can be applied for predicting slope stability when typhoons are expected to bring heavy rainfall and should be significant in slope disaster prevention.
