韩城矿区是1970年开始建设的新兴煤炭工业基地,也是受奥灰岩溶水威胁较严重的矿区之一。全矿区在已探明的13亿吨工业储量中,有11.2亿吨在奥灰岩溶水水位以下,占总工业储量的86.1％,在现有的6对生产矿井中,全部存在带压开采问题。尤其是本矿区的主要可采层11号煤层,由于距奥灰岩最近,几乎全部不能开采。因此,如何解决奥灰岩溶水的威胁,合理开发利用煤炭资源,就成了我们迫切需要解决的问题。本文仅就该矿区在带压开采条件下巷道布置层位和11号煤层开采的可能提出拙见,不妥之处请商榷。
Hancheng mining area is a burgeoning coal industry base started construction in 1970 and is also one of the mining areas threatened by ores of limestone. In the whole mining area, of the 1.3 billion tons of industrial reserves that have been proven, 1.12 billion tons are below the ores of dissolved limestone, accounting for 86.1% of the total industrial reserves. In the existing 6 pairs of production mines, there are all problems with pressure mining . In particular, the No. 11 coal seam, the main recoverable layer of the mine, can not be mined almost entirely due to the recent outgrowth of the Ordovician limestone. Therefore, how to solve the threat of the limestone karst water and to develop and utilize the coal resources reasonably has become an urgent problem that we need to solve. This article only on the mining area under the conditions of pressure mining roadway layout and No. 11 coal seam mining may be humble opinion, the wrong place to discuss.
