| 摘 要： | 以矿井地质勘探期间和实际开采中的瓦斯资料为基础,从煤体性质出发,通过吸附常数测定、工业参数及孔隙测定等实验结果,运用瓦斯地质学相关理论,全面系统的研究前期成煤环境、后期地质构造等因素对赵楼煤矿3#煤煤层瓦斯赋存的影响,并对特殊地质条件下的瓦斯赋存特点进行分析;研究认为3#煤煤层生成瓦斯和吸附瓦斯能力较差,虽然煤田的沉积环境及围岩条件利于瓦斯的赋存,但后期对瓦斯的赋存及分布起着区域性控制作用的地质构造运动利于瓦斯的逸散,造成赵楼煤田整体上瓦斯含量较低,局部特殊条件下瓦斯赋存存在不确定性,需要结合地质背景具体分析。

| Abstract: | Based on the gas data during geological exploration and mining period,combined with experimental results of adsorption constant,porosity and industrial properties,the paper analyzed the factors affecting gas occurrence from coal properties to coal-forming environment and geological structures by using methods of gas-geology;and it pointed out that,though the coal-forming environment is conducive to gas occurrence,the geological structure is the controlling factors causing low gas occurrence in No.3 coal seam.Under the special condition,gas occurrence should be analyzed with geological background concretely. |
