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
rock burst monitoring in coal mine huafeng。
关键词：立井；上下山开采；暗立井延伸；双巷掘进；中央并列式
ABSTRACT
This design can be divided into three sections: general design, monographic study and
translation of an academic paper.
The general design is about a 1.8 Mt/a new underground mine design of Zhangshuanglou
coal mine. It’s about 10.27 km on the strike and 3.29 km on the dip,with the 32.04 km2 total
horizontal area. The minable coal seam of this mine is only 7# with an average thickness of 5.0
m and an average dip of 18°. The proved reserves of this coal mine are 224.678 Mt and the
minable reserves are 153.331 Mt, with a mine life of 65.53 a.The geological condition of the
mine is relatively simple. The normal mine inflow is 200 m3/h and the maximum mine inflow is
280 m3/h. It is bituminous coal 44 with low mine gas emission rate and coal spontaneous
combustion tendency, and it’s a coal seam liable to explosion.
Based on the geological condition of the mine, I bring forward four available project in
technology. The fourth project is the best comparing with other three project in technology and
economy. The first level is at -600 m, The second level is at -1000 m, Because a major fault lies
in the center of mine field, the mine field is divided into the north section and the south section,
the south section is one level service scope, and the north section is two level service scope.
Designed first mining district makes use of the method of preparation in mining area, the
length of working face is 170 m, which uses fully-mechanized coal mining technology, and fully
caving method to deal with goaf. The working system is “three-eight”,with two teams mining,
and the other overhauling. Every mining team makes three working cycle, with six working
cycle everyday. Advance of working cycle is 0.865 m, and quantity of 5632.603 ton coal is
makedeveryday.
Main roadway makes use of belt conveyor to transport coal resource, and mine car to be
assistant transport. Main shaft makes use of skip to transport coal resource, when subsidiary
shaft makes use of cage to be assistant transport. In the prophase of mining the mine makes use
of centralized ventilation method,when in the evening of mining the mine makes use of areas
ventilation method. At the easy time of mine ventilation, the total air quantity is 78.78 m3 per
second, the total mine ventilation resistance is 2035.88 Pa, the coefficient of resistance is 0.328
N·s2/m8, equivalent orifice is 2.08 m2. At the difficult time of mine ventilation, the total air
quantity is about 78.78 m3 per second, the total mine ventilation resistance is 2182.84 Pa, the
coefficient of resistance is 0.352 N·s2/m8, equivalent orifice is 2.01 m2. The cost of the designed
mine is 110 yuan per ton.
The translated academic paper is about EME in the rock burst .
Keywords：shaft; up-dip and down-dip minging; double thunnel drivage; centralized
