| 摘 要： | 通过对贺西煤矿地质构造、地质勘探钻孔探明的瓦斯基础参数分析发现煤层埋藏深度是影响该矿瓦斯含量和压力的控制因素。统计分析表明二者分别与煤层的埋藏深度成近似线性关系,并由此预测了生产采区生产区域的瓦斯含量和压力,预测值与实测值误差小于20%。贺西煤田的瓦斯风带深度为225 m,瓦斯带内瓦斯含量和压力的变化范围分别为5.27~8.64 m3/t和0.1~1.45 MPa。研究结论能作为瓦斯抽放设计的依据。 |

| Abstract: | The gas content and pressure were found to be controlled mainly by burying depth of coal bed through analysis of geological structure of coal seam and methane parameters of geological prospecting holes in Hexi mine.The statistical analysis shows that both gas content and gas pressure are linearly related to the depth.The prediction of the content and pressure in working regions shows a deviation of less that 20% between predicted and measured values.The depth of weathered coal zone is 225 m,the gas content ... |
