根据钻孔资料和矿井生产资料,对青东矿主采煤层8-2煤层滑构造发育特征进行研究,并采用模糊综合评判法对其复杂程度进行定量评价。结果表明:青东矿8-2煤层滑构造主要表现形式为断裂式层间滑动,在矿区中、东部发育强烈,与构造煤的展布重叠区域大,说明采用模糊综合评判法所得结果是可靠的。
According to the borehole data and mine production data, the development characteristics of coal seam 8-2 coal seam in Qingdong coalmine are studied, and its complexity is quantitatively evaluated by fuzzy comprehensive evaluation. The results show that the main slip-tecton of the 8-2 coal seam in Qingdong Mine is mainly fault-type interlaminar slip. In the middle and eastern part of the mine, it is strongly developed and overlaps with that of tectonic coal, indicating that the result obtained by fuzzy comprehensive evaluation is reliable of.
