某矿区瓦斯地质与瓦斯防治方案探析

通过井田瓦斯地质资料,分析了构造演化、地质构造、煤系地层岩性、煤层埋深与煤层厚度对瓦斯赋存产生的作用。研究表明,构造演化是影响区域瓦斯赋存的首要因素,在井田内,随着煤层埋藏深度的增加,煤层瓦斯含量逐渐升高,并且是影响瓦斯赋存的主控因素,地质构造、煤系地层岩性同样发挥着重要作用。在某矿的瓦斯地质基础上根据《防治煤与瓦斯突出规定》探析了某矿的瓦斯地质问题,并探讨了安全生产中应注意的问题。

Mine District Gas Geology and Gas Control Scheme Analysis

Based on the well field gas geological data to analyze the influences of structural evolution,geo-logical structure,coal measure strata lithology,coal buried depth and coal thickness on the gas occurrence. The research shows that the structural evolution is primary factor influencing the regional gas occurrence;in the well field,the coal seam gas-bearing capacity is increase along with the increase of coal buried depth and it's the main controlling factor influencing gas occurrence;geological structure and coal measure strata lithology also have great influences.Explore and analyze the gas geology problem based on gas geological basis of one certain mine and according to Coal and Gas Outburst Prevention and Control Stipulation and discuss the problems to be paid attention to in safety production on this basis.
