采矿工程毕业设计（论文）鸡西矿业集团新发煤矿1.2mta新井设计[2]【全套图纸】.doc

摘 要
，一共有3层可采煤层，分别为29#、24#、4#，。煤层工业牌号为1/3焦煤，，。
本矿井设计采用以双立井开拓，划分为两个水平，共十八个采区，双翼开采，两个工作面达产，29#、24#、4#分层开采。集中大巷采用10t架线式电机车牵引，3t底卸式矿车运输，采煤方法为走向长壁采煤法，采煤工艺为普通机械化采煤工艺。顶板处理方法为全部跨落法。
关键词 矿井设计 立井开拓 走向长壁采煤法

Abstract
This design mine is opened by the Xinfa coal mine new mine design for Jixi Mining bureau, This mine altogether has 3 level that can adopt coal seam，which is 29#、24#、4#, The total thickness of coal seam is coal seam industry quality is 1/3 of coking coal, design well field recover resources , the design length of service is years.
This design mine uses the double vertical shaft development,
divided as two mining levels, altogether 18 districts, biplane wing mining, two working face reach to produce, 27#、24#、4# consociation gathering main roadway uses 10 ton wire laying type electric locomotive hauling, 3 ton drop-bottom mine car transportation, the mining coal method is longwall coal mining method, the mining coal craft is the mechanized mining roof processing method is all cross falls the law.
Key word Mine design Vertical shaft development
Longwall coal mining method
