摘要
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,并在安徽省淮南市新集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。
Reasonability on the application of hydrofracture to measuring the strength of coal seams is investigated in the paper.The tests are successful in probing the strength of the coal pillar in Xinji Coal Mine.The methods to obtain the parameters are more accurate then in the lab.The application of the parameters obviously decreases the width of the pillars for water blocking and increase the mineable coal reserve for the mine.
