摘要
文章回顾了京西煤田已往地质勘查及开采状况。结合1991—1992年对京西斋堂地区滑脱构造验证的结果,认为今后京西煤田的勘探工作应主要投向隐伏煤田,特别是髫髻山—庙安岭向斜和百花山向斜轴部的火山岩覆盖区更应当作今后工作的主要靶区。指出地质研究工作应首先考虑继续对斋堂地区滑脱构造的验证,进一步对滑脱面下煤层赋存进行各方面的定向研究。最后在京西煤田划分出了六个含煤地层勘探预测区。
The geological prospecting and mining history has been reviewed, in the coal basin of western Beijing. The confirmation result of decollement structure in the Zhaitang district of western Beijing in 1991 to 1992 tell us, that the concealed coalfields should be the major prospecting work in the future in the coal basin of western Beijing. Especially the Diaojieshan—Miaoanling syncline and Baihuashan syncline axis, where covered by volcanic rocks, should be the major practice districts in the further work. The first step should be continue confirmed the decollement structure of Zhaitang district, especially the exist of coal bed under the decollement plan. Six coal-bearing strata prospecting prediction district also have been enclosed.
