在含石油岩层下采煤,是我国当前煤炭工业生产中出现的一个新问题。陕西铜川焦坪矿区所属各矿井如崔家沟煤矿、下石节煤矿、陈家山煤矿等均有不同程度的石油与煤共存情况。根据了解,除铜川焦坪矿区外,运有邠县煤田、黄陵煤田、内蒙长汉沟煤田、辽宁清河门煤矿等都不同程度地存在着油、煤共生情况。在采煤过程中,赋存于顶板含油层中的原油通过顶板裂隙渗入采煤工作面和采空区,将
Coal mining under the rock bearing strata is a new problem appearing in the current coal industry in our country. All coal mines owned by Shaanxi Tongchuan Jiaopeng Mine, such as Cuijiagou Coal Mine, Xiaoshidai Coal Mine and Chenjiashan Coal Mine, have different degrees of coexistence of oil and coal. It is understood that, in addition to Tongchuan Jiao Ping mining area, there are Yuxian Coalfield, Huangling Coalfield, Inner Mongolia Changhangou Coalfield, Liaoning Qinghemen Coal Mine and so there are varying degrees of oil and coal symbiosis. During the coal mining process, the crude oil in the top oil layer infiltrates into the coal mining face and the goaf through the cracks in the roof.
