综采工作面薄煤带范围精细综合物探

摘要
通过对矿井直流电法和槽波地震法探测煤层变薄带方法原理的研究,发现槽波经过断层或煤层变化带时槽波能量会在煤层变化区域聚集,槽波初至时间对煤层局部变薄带有明显反应,由此可得到较准确的煤层变薄带平面分布范围;矿井直流电法对被相对低阻围岩充填的煤层变薄带呈明显低阻反映,它不仅能探测并圈定工作面内部的煤层变薄带还能探测单个巷道一侧的煤层变薄带范围。使用2种方法对黄陵一号矿1001工作面内煤层变薄带进行了探测,2种方法综合解释互为补充,圈定了小于1.6 m不能综采的范围,验证效果良好。
Through studying the method and principle of using mine direct current resistivity method and channel wave seismic exploration technique to explore coal bed thinning belt,we find that when channel wave go through the area with fault or changed seams its energy will gather to this area,its first arrival has significant response to the thinning coal area,thus the plane distribution of thinning coal area could be got accurately. Mine direct current resistivity method has significant response of low resistivity to the thinning coal area which was filled with relative low resistivity surrounding rock,it not only can detect and delineate the range of thinning coal area within fully mechanized mining working face,but also the range of thinning coal area within single side of roadway. Using these two methods to detect thinning coal area at 1001 working face in Huangling No. 1 Coal Mine,these two methods are complementary integrated interpretation,and delineate area that coal seam is thinner than 1. 6 meter that could not be mined,and which is verified well.
