摘要
煤层瓦斯赋存规律研究和突出区域预测指标的准确选取是确保煤矿安全生产的关键。在分析玉舍煤矿瓦斯地质资料的基础上,结合煤层相关参数的测定,探讨了地质构造、岩浆侵入、煤层围岩、煤层埋深等地质因素对煤层瓦斯赋存、分布规律的影响。分析了各因素与瓦斯赋存的关系,得出结论:地质构造、煤层围岩、煤层埋深是影响瓦斯赋存的主控因素。
Studying on distribution rules of coal seam gas and accurately selecting prediction index of outburst region are key works to guarantee mine safe production.Through analyzing the gas geologic data in Yushe Coal Mine,based on the field measurement for the related parameters of the coal seam,this paper discussed the geologic factors influencing coal seam gas occurrence and distribution regularity,such as geological structure,magmatic instrusion,coal-bed surrounding rock,buried depth of coal-bed and so on.It also analyzed the relationship between all factors and coal-bed gas occurrence regularity,and the conclusion was drawn that the main controlling factors affecting coal-bed gas occurrence are geological structure,coal-bed surrounding rock and buried depth of coal-bed.
