摘要:用地质观点研究煤层瓦斯赋存已获得实践检验,瓦斯的赋存及涌出与地质因素密不可分.在收集并整理黄陵二号煤矿井田地质资料和瓦斯资料的基础上,分析了井田地质构造特征,结合瓦斯地质理论,研究地质构造、煤层顶底板岩性、煤层埋藏深度、水文地质条件等因素对瓦斯赋存的影响,融合矿井勘探及生产期间实测瓦斯含量数据,采用瓦斯地质统计法建立回采面绝对瓦斯涌出量与煤层瓦斯含量的关系式,并以此对矿井未采区的瓦斯涌出量进行了预测.

Abstract:It is feasible of researching gas occurrence in geologic opinion.There is close relationship between gas occurrence and geologic factors.Collecting the geologic and gas data systematically in No.2 coal mine in Huangling, analyze the law of geologic structure.Associating with the gas-geology theory, analyze the influence factors of gas occurrence, such as the geologic structure, the rock character of roof and floor, the burial depth of coal-bed, hydrogeologic condition and so on.Associating with gas content data during exploration and production, draw the gas content contour.Establish relational expression module about stope gas emission rate and gas content by gas-geology method, and forecast the gas emission rate in the original region.
