The geological environment is important for the development of coal enterprises. In Guqiao coalmine, information mining subsidence, terrain landform, gangue utilization, mine water treatment and several on-site investigations have been analyzed. It holds that its can be evaluated from three aspects, i.e., disasters, landform destruction, influence on soil environment. results show activities se...
The forecasting slope deformation potential is required to evaluate slope safety during open-pit mining, allowing us to formulate and promote effective emergency strategies in advance to prevent slope failure disasters. Although fractal models have been used to predict slope deformation, such limitations as low prediction accuracy, poor stability and the requirement for large amounts of data mu...
The most important aspect of the MINER Act is providing reliable communication for miners before and after tragic accidents. Reliable communication has always been a challenge in underground mines due to changing topologies and harsh environment. In addition, disasters disable electricity and communications cables, block tunnels and cause fire. These may damage the communication infrastructure ...
Sudden ground pressure disasters caused by deep mining such as rock burst and cave-in are major hidden dangers affecting safety production underground mine. The safe stable operation of monitoring platform is great significance for mine production. However, many small medium-sized enterprises make slow progress in the construction online due to limitations enterprise scale, capital capacity oth...
Rock burst is one of the most serious dynamic disasters in process coal resources mining, order to study its occurrence mechanism and characteristics impact on roadways. Based No. 25110 working face Yuejin Mine Yi Coal 21032 return air uphill event Qianqiu Mine, combined with geological conditions, shock location, source waveform, this paper uses numerical simulation inverse response roadway su...
Abstract There are abundant limestone resources in Weibei area. However, under the influence of a complex geological environment and harsh external environment, they often suffer from various types serious disasters, which seriously threaten safety people mining area development resources. Therefore, it is urgent to carry out relevant governance. Firstly, combined with field engineering data ty...
Fully mechanized top-coal caving mining with high height, hard roofs and strong pressure are popular in the Shendong area, China. The occurrence of dynamic disasters, such as rock burst, coal gas outburst, mine earthquakes goaf hurricanes during exploitation process under roof conditions, pose a threat to safe production mines. In this study, characteristics overburden fracture fully height stu...
A coal-rock dynamic disaster is a rapid instability and failure process with effects huge disastrous consequences that occurs in mass under mining disturbance. Disasters lead to catastrophic consequences, such as mine collapse, equipment damage, casualties. Early detection can prevent the occurrence of disasters. However, due low accuracy anomaly detection, disasters still occur frequently. In ...
