钱营孜煤矿2.4Mta新井设计.docx

1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为钱营孜煤矿2.4 Mt/a新井设计。钱营孜煤矿位于安徽省宿州市西南，区内有南坪集至宿州市的公路和四通八达的支线与任楼、许疃、临涣、童亭、桃园等矿井相连。青疃芦岭矿区铁路支线从勘查区南部由西向东穿过，向东与京沪线、向西与濉阜线沟通。合徐高速公路从勘查区东北部穿过，交通十分便利。井田走向长度约6 km，倾向长度约3.2 km，面积约35.08 km2。主采煤层为32号煤层，平均倾角为12，平均厚度为2.89 m。井田工业储量为159.69 Mt，可采储量为99.32 Mt，矿井服务年限为51 a。矿井正常涌水量为434 m3/h，最

2、大涌水量为885 m3/h。矿井绝对瓦斯涌出量为1.72 m3/min，属于低瓦斯矿井。根据井田地质条件，提出四个技术上可行的开拓方案。方案一：立井单水平开拓上山开采，岩石大巷开拓；方案二：立井单水平开拓上山开采，煤层大巷开拓；方案三：立井两水平开拓上山开采，岩石大巷开拓；方案四：立井两水平开拓上山开采，煤层大巷开拓。通过技术经济比较，最终确定方案一为最优方案。水平标高-720 m。设计首采区采用采区准备方式，工作面长度200 m，采用综采一次采全高采煤法，矿井年工作日为330 d，工作制度为“三八制”。大巷采用底卸式矿车运输，辅助运输采用矿车运输。矿井通风方式为分区对角式。专题部分题目是工作

3、面大推进度运输保障技术，锚网支护是这类巷道的主要支护手段。阐述了沿空巷道上覆岩层结构、围岩应力分布、围岩变形的一般规律。并通过对现场实测数据的整理分析，总结了类似条件下巷道的矿压显现规律，以指导沿空巷道的支护设计。翻译部分题目是水泥浆性能对充分注浆锚杆拉拔承载能力的影响。关键词：钱营孜煤矿；立井；采区布置；一次采全高采煤法；分区对角式；双巷掘进ABSTRACTThis design can be divided into three sections: general design, monographic study and translation of an academic paper.
