1、摘 要本设计由三个部分组成：一般部分、专题部分和翻译部分。一般部分为燕子山矿4.0Mt/a的新井设计。燕子山矿位于山西省大同市境内，区内交通方便。井田东西长9.0km，南北宽7.1km，面积55.2936km2。燕子山矿北以十里河南岸为界，东界为四台沟矿和大同市地方煤矿，南界为马脊梁矿，西界外为东周窑矿。燕子山矿主采煤层为5号煤层，煤层平均倾角4.5，煤层平均厚约5.8m。井田工业储量为607.07Mt，可采储量432.81Mt，矿井服务年限为77a。井田地质条件简单。矿井正常涌水量为135.2m3 /h，最大涌水量为269m3 /h；矿井绝对瓦斯涌出量为6.6m3 /min，属低瓦斯矿井；煤
2、层有自燃发火倾向，煤尘具有爆炸危险性。根据井田地质条件，提出三个技术上可行开拓方案。经过技术经济比较，选取最优方案为：主斜井副立井单水平开拓方案。水平标高+880m。 设计首采区采用带区准备方式，工作面长度215m，采用一次采全高采煤法。矿井采用“三八”制作业，两班生产，一班检修。生产班每班6刀，日进12刀，循环进尺0.8 m，日产量12121.2t。运输大巷采用胶带输送机运煤，辅助运输大巷采用无轨胶轮车。主斜井采用胶带运输机提升煤炭；副斜井设计采用罐笼提升设备、人员、材料和矸石。矿井采用中央分列式通风。专题部分题目是防止煤层自燃的分析。翻译部分是一篇关于综放开采工作面支架与围岩的相互作用特征
