水压致裂强度测试法在断层防水煤柱合理留设中的应用

Application of Hydraulic Fracturing Method to Rational Set-Up of Water Prevention Coal Pillar in Mine Fault

论文研究了水压致裂原位强度测试方法在煤层强度测试中应用的适用性,并在太原东山煤矿断层防水煤柱强度测试试验中取得了成功,参数获取方法较实验室更为合理,该参数使得防水煤柱宽度大为缩小,显著地增加了煤矿的可采储量。

The paper had a study on the suitability of the hydraulic fracturing in - situ strength measuring method applied to the seam strength measurement. The hydraulic fracturing in -situ strength measuring method had a successful applieation to the test of the water prevention coal pillar strength measurement in the fault of Taiyuan Dongshan Mine. The parameter obtained method could be more rational than the in - door lab. The parameters obtained could make the width of the water prevention coal pillar highly reduced and thus the mineable coal reserves of the mine could be obviously increased.
