1 概况 二十二采区为杨村矿—273水平下山首采区,采区西至—273m运输大巷,南与二十一采区相邻,北与二十三采区相邻,东至井田边界。由于二十二采区的特殊地质条件,将采区分为F断层以东和断层以西两大块段(见图1)。F_(22-7)断层以东块段地质及水文地质条件复杂,暂缓开拓,不作论述。以西块段为目前的主要接续采区,16上、17两煤层地层自新至老分别为第四系、二迭系山西组、石炭系及奥陶系。第四系厚196.18m,二迭系残厚85.95m,石炭系太原组厚度140～165m,含
1 Overview The 22nd mining area is the first coal mining area down the mountain at -273 level in Yangcun Mine. The mining area is to the -273m transportation lane to the west of the mining area, adjacent to the 21th mining area in the south and adjacent to the 23th mining area in the north. To the Ida boundary. Due to the special geological conditions of Twenty-second Mining Area, the mining area is divided into two sections, east of F fault and west of fault. (See Figure 1). The geological and hydrogeological conditions in the east of section F_ (22-7) of the fault are complicated and are temporarily delayed for exploration. The west section of the block is the main continuation of the mining area. The 16th and 17th coal seam strata have been reconnected to the Quaternary and Permian, respectively, to the Shanxi Formation, Carboniferous and Ordovician. Quaternary thickness 196.18m, Permian system residual thickness 85.95m, Carboniferous Taiyuan Formation thickness of 140 ~ 165m, with
