海孜矿复杂地质对煤层瓦斯赋存影响分析

Influence Analysis of Complex Gas Geologic Features in Haizi Coal Mine on Coal Seam Gas Occurrence

中文摘要英文摘要

掌握煤层瓦斯赋存规律可以为煤矿采取合理瓦斯治理措施提供科学依据。运用瓦斯地质理论,依据瓦斯基础参数,结合海孜煤矿复杂地质特征,分析影响海孜煤矿八六采区主采煤层瓦斯赋存的主要地质因素。研究发现,层状岩浆岩控制着八六采区主采煤层的瓦斯赋存,煤体变质程度高,吸附能力大,瓦斯含量大;而大刘家正断层控制着八六采区西翼主采煤层瓦斯赋存,大刘家正断层附近煤岩体呈角砾和糜棱碎屑状,煤岩体破碎,强度降低,裂隙发育,存在着瓦斯排放带。

Master gas occurrence regularity in order to provide scientific basis for taking reasonable gas control measures. Using gas geological theory, based on gas-based parameters, combined with the complex gas geological features in Haizi coal mine, the paper dicussed the influence of the main geological factors on gas occurrence regularity of the primary mineable coal seam in 86 mining area in Haizi coal mine. The results showed that layered igneous rocks controled gas occurrence of the primary mineable coal seam,and led to high rank coal,large adsorption capacity and larger gas content. The coal and rock mass near normal fault was brecciated and mylonitic debris-like, crushing, strength reduction and fracture development, near which there is a certain width of the zone of gas emissions.
