贵州谷里煤矿地质特征及开采技术条件分析

Analysis of Geological Characteristics and Mining Technical Conditions of Guli Coal Mine in Guizhou Province

谷里煤矿目前对煤层发育特征和开采技术约束条件(尤其是工程地质条件)没有开展研究工作,不利于后期煤矿的开发工作。文章采用钻探、测井、坑道测量及样品测试等工作方法和手段,结合矿区外围其它矿床地质特征和开采条件,对谷里煤矿的地质特征、煤层发育情况、工程地质条件和瓦斯、煤尘爆炸性、自然倾向性等开采技术条件进行了探讨。

At present,there is no research work on the development characteristics of coal seam and the constraints of mining technology(especially the engineering geological conditions)in Guli Coal Mine,and the development work of coal mine in the later stage is not utilized.In this paper,the geological characteristics,coal seam development,engineering geological conditions and gas of Guli Coal Mine were studied by means of drilling,logging,tunnel survey and sample testing,combined with the geological characteristics and mining conditions of other deposits outside the mining area.The mining technical conditions such as explosive coal dust and natural tendency were discussed.
