摘 要
本设计包括三个部分：一般部分、专题部分和翻译部分。
一般部分为张双楼矿1.8 Mt/a 的新井设计。井田走向（东西）长平均约10.27 km，倾
向（南北）长平均约3.29 km，井田水平面积为32.04 km2。主采煤层一层，即7#煤层，平
均倾角18°，厚约5.0 m。井田工业储量224.678 Mt，可采储量153.331 Mt，矿井服务年限
为65.53 a。井田地质条件简单；表土层平均厚度约50 m；矿井正常涌水量为200 m3/h，最
大涌水量为280 m3/h；煤层硬度系数2～3，煤质牌号为气煤44；矿井绝对瓦斯涌出量为
3.73 m3/min，属低瓦斯矿井；煤层有自燃发火倾向，发火期3～6 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。通过技术经济比较，最终确定方
案四为最优方案。将主采煤层划分为两个水平，一水平标高—600 m，二水平标高—1000 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170 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3 个循环，
日进6 个循环，循环进尺0.865 m，日产量5632.603 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16 t 双箕
斗带平衡锤提煤，副井装备一套带平衡锤的1.5 吨固定车厢式矿车双层四车加宽罐笼。矿
井采用中央并列式通风。通风容易时期矿井总需风量78.78 m3/s，矿井通风总阻力2035.88
Pa，风阻0.328 N·s2/m8，等积孔2.08 m2，矿井通风容易。矿井通风困难时期矿井总风量
78.78 m3/s，矿井通风总阻力2182.84 Pa，风阻0.352 N·s2/m8，等积孔2.01 m2，矿井通风也
较容易。设计矿井的吨煤成本110 元。
专题部分题目是煤岩冲击倾向性及物理力学性质测定。以口孜东煤矿的生产中的煤岩
样测定了口孜东顶板岩层的冲击倾向性和顶板岩层的物理力学性质。
翻译部分是一篇关于电磁辐射在冲击矿压中的应用的论文，英文原文题目为：EME

关键词：立井；上下山开采；暗立井延伸；双巷掘进；中央并列式
