摘　　要：以黄陵矿区高瓦斯矿井瓦斯灾害治理为背景,通过测定同一煤层的不同或相同工作面之间煤的真密度、视密度、孔隙率、瓦斯吸附常数a、b值以及水分、灰分、挥发分等参数,研究黄陵矿区高瓦斯矿井残存瓦斯含量、瓦斯压力与各项测试值之间的关系,给出绝对瓦斯压力在0.1~5 MPa之间的瓦斯吸附量,为工作面瓦斯含量推算和预测提供数据基础,并根据瓦斯含量、煤的吸附量、吸附能力和孔隙率等参数简单分析了黄陵矿区各矿井生产工作面之间煤层瓦斯的抽采难易程度。Taking gas disaster control of high gas mine in Huangling mining area as background,by measuring basic parameters of gas in each mine,the relationship between residual gas content,gas pressure and various test values of high-gas mines in Huangling mining area was studied,and the gas adsorption amount between 0.1-5 MPa of absolute gas pressure was given,which provides data basis for predicting gas content in working face.According to the parameters of gas content,coal adsorption capacity,adsorption capacity and porosity,the difficulty degree of gas extraction in coal seams of Huangling mining area is simply analyzed.
