摘　　要：为解决底板富水煤层瓦斯压力难以准确测定的问题,提出了煤层瓦斯压力精准测定方法,通过合理封闭围岩裂隙,消除围岩水的影响,并与常规测压孔进行对比验证,实现了底板富水煤层瓦斯压力的精准测定。应用该方法在宝雨山矿1702工作面进行了煤层瓦斯压力测定,高效、准确、经济地获得了该区域的煤层瓦斯压力数据。研究表明,底板富水煤层瓦斯压力精准测定方法能有效封闭围岩裂隙,消除围岩水的影响,为瓦斯压力的精准测定提供了保证。It is difficult to accurately measure the gas pressure in coal seam with water-rich floor.For this reason,an accurate measurement method of gas pressure in coal seam is put forward.By reasonably closing the cracks in the surrounding rock,this method eliminates the influence of the surrounding rock water.On this basis,compared with the conventional pressure hole,the accurate measurement of gas pressure in coal seam with water-rich floor is realized.This method is used to measure the gas pressure in coal seam in 1702 working face of Baoyushan coal mine.The coal seam gas pressure data in this area are obtained efficiently,accurately and economically.The study shows that the accurate measurement method of gas pressure in coal seam with water-rich floor can effectively close the cracks in surrounding rock and eliminate the influence of surrounding rock water,which provides a guarantee for the accurate measurement of gas pressure.
