摘要
煤矿地质探测工作中对断层构造的探测十分重要,提前探测出断层位置及赋存参数对确保矿井安全生产具有重要意义。为进一步验证大柳塔煤矿五盘区DDF2断层构造,在地面布置施工钻孔3对6个(D304、D305、D306、D307、D308、D309),进一步查明DDF2断层的断距、延展方向及延伸长度,为52506工作面开采提供可靠的依据。结果表明:DDF2断层存在,且位于D304钻孔和D305钻孔之间5-2煤底板断层落差为0~5.01 m,位于D306钻孔和D307钻孔之间5-2煤底板断层落差为3.60 m。DDF2断层活动从东南向西北方向逐渐加强,断层活动开始于东南方向,逐渐向西北方向迁移、加剧到最后尖灭。
It is very important to detect the fault structure in the geological exploration of coal mine.It is important to detect the fault location and occurrence parameters in advance to ensure the safe production of coal mine.In order to further verify the structure of DDF2 fault in the fifth panel of Daliuta coal mine,3 pairs of 6 construction boreholes(D304,D305,D306,D307,D308,D309)are arranged on the ground,and further find out the fault distance,extension direction and extension length of DDF2 fault,so as to provide a reliable basis for the mining of 52506 working face.The results show that DDF2 fault exists,and the 5-2 coal floor fault drop between borehole D304 and borehole D305 is 5.01 m,and the 5-2 coal floor fault drop between borehole D306 and borehole D307 is 3.60 m.DDF2 fault activity gradually strengthened from southeast to northwest,started from southeast,gradually moved to northwest,intensified to the final pinch out.
