为了确定煤矿冲击地压的地质动力环境,利用GIS对中国Ⅰ、Ⅱ级活动地块和活动断裂与冲击地压矿井的空间分布相关性进行了分析,论述了冲击地压孕育的地质动力条件和冲击地压显现的能量来源,并以抚顺矿区为例分析了冲击地压的地质动力环境。研究结果表明:我国63%的冲击地压矿井处于Ⅰ、Ⅱ级活动地块的边界及其影响带上,东北亚地块、华北地块、鄂尔多斯地块的冲击地压矿井位于地块周缘,华南地块的冲击地压矿井处于地块内部;85%的冲击地压矿井处于活动断裂的影响范围内,东北亚地块、华北亚地块、华南亚地块具有相似的规律。地质动力环境是冲击地压系统的能量来源和冲击地压孕育的地质动力学条件,矿区/矿井冲击地压显现的总体强度或释放的总体能量取决于其地质动力环境,抚顺矿区F1断层和F1A断层组成的浑河活动断裂是矿区冲击地压的地质动力环境。

in order to detemine the geocgic dynanic environment f the mine stra pressure bump.,the G(S was applied to the analysis on the correlation of Chinal Grade and Ⅱ Grade active crutal blocks and active mine pressure bump with the space distribution of the mine with mine prssure bump. The paper stated the geoogic dynamic cordtions of the mine pressure bump development and the energy sources of the mine pressure bump behaviors and based on Fushun Mining Area as acase.the geologic dynamic environment ofthe mine prssure bump was analyzed. The stuty results showed that63% of the pressure bunp mines in China were at theboundary and the ifuence zone of china l and Ⅱgrade activ crustal blocks. The mine prssure bump mines in Norheast Asia Block,Norh China Block and Oordos Block were lcated at the peripheres of the blocks and the mine pressure bump mines in South China Block werelocated in the interor ofthe bock.There were 85% ofhe mine pressure bump mines lcated within the active facturing infuence scope and NortheastAksia Block. North China Block and Scuth ChinaBock would have the smiar law. The geologic dynamic environment would be the enegy sources of the mine pressure bump system and the geocgi dynamics conditon of the mine pressurbump development.The total strength of the mine pressure bunp behavior or the total energy released fom the mining rea mine would be depended on the geologial dynamic environment and the Hunhe active fracture consisted with the F1 fultand F1 Alaut in fushun Mining Area woul be the geogic oynamic environment f te mine pressure bump in the mining area.
