摘要
,本矿区共有4层可采煤层,分别为7#、8#、23#、29# 。全区走向长5900m,宽2150m,。煤层工业牌号为1/3焦煤,,设计服务年限为61a。
本矿井设计采用双立井开拓,划分为三个水平,六个采区。东部基本采用双翼开采,西部多为单翼开采,一个工作面即可达产,达产时采区个数为一个。最上层距其他层较远采用独立上山布置,其余三层距离较近采用集中布置。大巷运输采用14t架线式电机车牵引,3t底卸式矿车运输,采用的采煤方法为走向长壁采煤法,采煤工艺为综合机械化采煤工艺。顶板处理方法为全部跨落法。

Abstract
This design mine is CHENGZIHE coal mine of the JIXI mineral industry Mts/a of the group new mine design, this mineral area totally has 4 F and can adopt coal seam and distinguish to 7#, 8#, 23#, 29# thicknesses with total coal seams to whole area alignment grows 5900 meters, the breadth is 2150 meters, area is the squares be thousand coal seam industrial card number is 1/3 coals, design well farmland of can adopt to keep to measure megatons, design length of service is 61 years.
This mineral well design adoption double signs well to expand, divide the line to three levels and 6 adopt eastern basic adoption double wing mine and the west much mines for the single wing and a work noodles can immediately reach to produce and adopt the area piece as 1 while reaching to topmost layer is apart from an other layer, the farther adoption independently climbs mountain a decoration, and the rest 3 F is apart from a nearer doption concentration a big lane conveyance adopts 14 line type electrical engineering cars to lead, 3 the ton bottom unload type mineral car conveyance, adopt of adopt a coal method to full-mechanized mining, adopt a coal craft prehensive the mechanization adopt a coal plank treatment for all across to fall a method.
