摘要
为有效治理大能量矿震,实现"有震无灾",以东滩煤矿六采区为研究背景,采用微震监测、理论分析、数据统计等手段对东滩煤矿63_上04和63_上05工作面回采期间矿震进行分析。大能量矿震发生往往与煤层上方坚硬岩层关系密切,硬厚岩层断裂是导致大能量矿震发生的主要因素,判定3上煤层上方90~180m硬厚砂岩为主导63_上04和63_上05工作面矿震发生的关键岩层;大能量矿震发生往往具有"见方"效应,可据此推演大能量矿震发生的时间和位置。
In order to effectively control the large energy mine earthquake, realize ＂earthquake without disaster＂, taking the six mining area of Dongtan coal mine as the research background, we use microseismic monitoring, theoretical analysis and data statistics to analyze the mine earthquake during the recoveryperiod of 63up 04 and 63up 05 working face of Dongtan Coal Mine. The occurrence of large energy mine earthquake is often closely related to the hard rock above the coal seam, and the fracture of hard and thick rock is the main factor that causes the occurrence of large energy mine. The hard and thick sandstone of 90- 180m above the 3up coal seam is the key rock that leads to the occurrence of ore shock in 63up 04 and 63 up 05 working face. The occurrence of large energy mineral earthquakes often has a ＂square＂ effect, which can be used to deduce the time and position of the occurrence of large energy mineral earthquakes.
