近距离煤层厚度及层间距探测研究

Research on the Detection of Seam Thickness and Interlayer Spacing in Close Distance

针对三交河矿计划开采的11~#煤层为局部可采煤层,采用了探地雷达、钻探、窥视等手段进行探查。通过探查得知10-201工作面下部11~#煤层厚度为2.2 m^3.7 m,与10~#煤层的层间距2.0 m^12.3 m,且往切巷方向层间距逐步减小,为下一步11~#煤层采掘布置提供了准确地质资料。

In this paper, ground penetrating radar, drilling, peeping and other means are used to explore the No.11 coal seam planned to be mined in Sanjiaohe mine, which is a local mineable coal seam. The exploration results show that the thickness of No.11 Coal Seam in the lower part of 10-201 working face is 2.2 m-3.7 m, and the interval between No.10 coal seam is 2.0 m-12.3 m, and the interval decreases gradually towards the roadway, which provides accurate geological data for the next mining layout of No.11 coal seam.
