贵州威宁县龙街向斜煤矿开采技术条件分析

Analysis of the Mining Technical Conditions of Longjie Syncline Coal Mine in Weining County of Guizhou

阐述了龙街向斜煤矿的水文地质条件、工程地质条件、环境地质条件,并对煤层的顶底板、煤层倾角、煤层瓦斯、地温等影响开采的技术条件进行初步分析。结果表明:煤层顶底板工程地质特性、水文地质特性及煤层瓦斯的富集对煤矿开采影响较大;矿区地温为正常区,其影响较小。

The hydrogeological conditions, engineering geological conditions, environmental geological conditions of Longjie syncline coal mine, and the technical conditions affecting mining such as the roof and floor of coal seam, inclination of coal seam,gas in coal seam and ground temperature are analyzed preliminarily. The results show that the engineering geological characteristics, hydrogeological characteristics and enrichment of coal seam gas of the roof and floor of coal seam impact on the mining greatly, and the ground temperature of the mine is normal, whose impact is smaller.
