摘要
根据阿刀亥煤矿1155工作面的基本情况,对急倾斜特厚煤层水平分段综放开采的采煤面瓦斯涌出来源进行了分析,根据瓦斯涌出的特征建立了急倾斜特厚煤层水平分段综放面瓦斯涌出量预测的数学模型。现场实测表明:理论计算误差范围满足工程需要,为阿刀亥煤矿制定对应的瓦斯治理措施提供了基础依据。
According to the basic situation of 1155 working face in Adaohao Coal Mine, the gas emission sources were analyzed in horizontal section fully mechanized top- coal caving, the gas emission prediction mathematical model was established, according to the gas emission features in horizontal sublevel fully mechanized top-coal caving face of steep extra-thick coal seam. The theoretical calculation results satisfied the engineering demand, according to the field measurement comparison, so as to provide basis for corresponding gas control measures of Adaohai Coal Mine.
