摘要
Abstract
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.关键词
