武家沟煤田已建三对矿井,总设计能力45万吨。武家沟井建于1921年,井型10万吨,至1980年底累计开采量219万吨,采深到306.8米。矿井内九层煤均已采光,煤源接替紧张,属于资源枯竭矿井。矿井外围的成煤远景如何?给矿井地质工作者提出了新的课题。笔者在研究区域构造控制聚煤作用的基础上,进行了矿井外围成煤预测工作,认为武家沟井东部和南部是成煤预测主要方向。经过二年的矿井地质勘探,收效显著,达到了预测目的。本文从聚煤古构造,含煤岩系的岩性、岩相和古地理成煤环境进行分析,提出冀北及武家沟井外围早、中侏罗世成煤条件的探讨,不
Wujiagou coalfield has built three pairs of mines, with a total design capacity of 450,000 tons. Wujiagou well built in 1921, well type 100,000 tons, to the end of 1980 a total of 2.19 million tons of mining, mining depth to 306.8 meters. Nine layers of coal in the mine have been lighting, the coal source to take over the tension, belonging to resource depletion mines. Coal mine peripheral coal prospect how to mine geology workers put forward a new topic. On the basis of studying the effect of controlling coal accumulation in the regional structure, the author carried out the prediction of coal formation at the periphery of the coal mine. It is believed that the eastern and southern parts of Wujiagou coal mine are the main directions of coal formation prediction. After two years of geological exploration in the mine, the effect has been remarkably achieved and the prediction has been reached. This paper analyzes the lithology, lithofacies and palaeogeomorphic coal formation of ancient coal-bearing coal-bearing structures, coal-bearing rocks, and puts forward the discussion on the conditions of coal formation in the early and middle Jurassic in the periphery of North Hebei and Wujiagou wells.
