寸草塔煤矿2^(-2)煤三盘区瓦斯参数测定

Determination on the gas parameters of third mining area in No.2^(-2) coal seam of Cuncaota coal mine

寸草塔煤矿属于低瓦斯矿井,2^(-2)煤三盘区未进行过瓦斯基本参数测定,只对瓦斯基本参数进行模拟,由于模拟数据存在误差,对瓦斯治理工作起不到一定的指导工作。文中简述了寸草塔煤矿三盘区瓦斯参数的测定方法和过程,测定三盘区煤层瓦斯压力、煤的瓦斯吸附常数测定及工业分析、煤层瓦斯含量等参数,为三盘区开拓及回采过程中瓦斯防治工作和矿井的安全生产提供理论依据。

By defining the measurement method and process of gas parameters in third mining area of Cuncaota coal mine,the parameters,such as gas pressure in the coal seam,gas adsorption constants,industrial analysis and gas content of coal seam,were determined,which can provide theoretical basis for gas prevention work and mine safety production in the third mining area.
