淮北孙疃矿180万吨新井设计.docx

1、摘 要本设计包括三个部分：一般设计部分、专题设计部分和翻译部分。一般部分为孙疃矿1.8 Mt/a的新井设计。孙疃煤矿位于安徽省淮北市濉溪县境内，其南与任楼矿井接壤，北与杨柳井田毗邻，东北距宿州市约23km。井田内有多条公路可至淮北市、宿州市和蒙城县。井田外东侧、西北侧和南侧分别有京沪铁路、濉阜铁路和矿区铁路青（疃）芦（岭）支线经过。交通十分方便。全井田南北走向长9.57km，东西倾斜宽35km，面积约40.7km2。主采煤层一层，即10号煤层，平均倾角17，厚约2.73 m。井田工业储量为308.24 Mt，可采储量234.41 Mt，矿井服务年限为93.01 a。井田地质条件简单。表土层平均

2、厚度50 m；矿井正常涌水量为383 m3/h，最大涌水量为520 m3/h；煤层硬度系数f=2.3；矿井绝对瓦斯涌出量为1.84 m3/min，属低瓦斯矿井；煤层有自燃发火倾向，发火期36个月，煤尘具有爆炸危险性。根据井田地质条件，提出四个技术上可行开拓方案。方案一：立井单水平上下山开采，水平在-550m, 煤层大巷；方案二：立井单水平上下山开采， 在-550水平，岩层大巷；方案三：立井两水平暗斜井开采 延伸至-900 m水平；方案四：立井两水平开采，立井井延伸至-900 m水平。通过技术经济比较，最终确定方案三为最优方案。将主采煤层划分为两个水平，一水平标高-550 m，二水平标高-900

3、 m，因井田走向大断层将井田分为南北两部分，井田南部为一水平服务范围，井田北部为二水平服务范围。设计首采区采用采区准备方式，工作面长度250 m，采用一次采全高采煤法，全部跨落法处理采空区。矿井采用“三八”制作业，两班生产，一班检修。生产班每班4个循环，日进8个循环，循环进尺0.8 m，日产量5454.54 t。大巷采用带式输送机运煤，辅助运输采用1.5 t固定箱式矿车。主井装备一套12 t双箕斗和一套12 t单箕斗带平衡锤提煤，副井装备一对3 t矿车双层单车罐笼带平衡锤担负辅助运输任务。矿井采用两翼对角式通风。通风容易时期矿井总需风量4150 m3/min，矿井通风总阻力1588 Pa，风阻

4、0.33 Ns2/m8，等积孔2.07 m2，矿井通风容易。矿井通风困难时期矿井总风量4150 m3/min，矿井通风总阻力2200Pa，风阻0.46 Ns2/m8，等积孔1.75m2，矿井通风中等困难。设计矿井的吨煤成本110 元/t。专题部分题目是浅谈寺河矿瓦斯治理和利用技术。采用地面抽采和综合利用翻译部分是一篇关于工作面煤尘控制的研究的论文，英文原文题目为：On the long wall of coal dust control 关键词：立井；上山开采；大采高；双巷掘进；两翼对角式ABSTRACTThis design includes three parts: general des
