刘庄矿含水砂岩下煤层瓦斯压力测定技术研究

摘要

According to the fact that coal seam sandstone roof is rich in water and water breakthrough point are difficult to master, at the same time there are a lot of cuttings through coal seam roof, all holes are angle of depression, so various water goes into the pressure chamber easily and it affects testing precision, the pressure test technology was researched, and the gas pressure is tested accurately by using this technology.%针对刘庄矿主采煤层顶板砂岩富水、见水点难以把握的特征，同时矿井揭煤多为顶板揭煤，测压孔全部为俯角孔，各类水源很容易进入测压室，影响测压的精度和效果等实际情况，进行了测压工艺的研究和应用，准确的测定出了煤层的瓦斯压力。
