大柳塔井5-2煤五、六盘区补充勘探成果分析

大柳塔煤矿大柳塔井5^-2煤五、六盘区利用直流电法勘探和三维地震勘探时,探测到存在异常区域和WF2正断层。为了对上述探测结果进一步验证,神东地测公司开展了补充勘探工程,施工探煤孔11个、物探异常验证孔8个、断层探测孔4个,总工程量为3308.15 m。通过对补勘成果分析,发现8个异常区验证孔,仅有1个钻孔(T46)与5^-2煤采空区贯通,且无水;验证了五盘区D区、E区物探WF2断层存在,确定了断层的走向、倾向、落差等断层要素;进一步掌握了大柳塔煤矿大柳塔井5^-2煤五、六盘区地质情况,达到了预期的目的。

Analysis on the supplementary exploration results of 5^-2 coal seam in Daliuta mine

By means of direct current exploration and three-dimensional seismic exploration,abnormal areas and WF2 positive fault have been detected in the fifth and sixth panel of 5^-2 coal seam in Daliuta mine.In order to further verify the detection results,the supplementary exploration projects were carried out.Through the construction of 11 coal exploration holes,8 geophysical anomaly verification holes and 4 fault detection holes,the total work amount reached 3308.15 m.Through the analysis of the supplementary exploration results,it is found that only one borehole(T46)of the 8 geophysical anomaly verification holes is connected with the 5^-2 coal goaf,verifies the existence of the WF2 fault in the fifth panel area,determines the fault elements such as the strike,tendency and drop of the fault,grasps the geological conditions of the 5^-2 coal seam in Daliuta mine,and achieves the expected purpose.
