摘 要

本设计包括两个部分：一般部分和专题部分。

一般部分为五阳二矿5Mt新井设计，共分10章：1.矿区概述及井田地质特征；2.井田境界和储量；3.矿井工作制度及设计生产能力；4.井田开拓；5.采区巷道布置；6.采煤方法；7.井下运输；8.矿井提升；9.矿井通风与安全；10.矿井基本技术经济指标。

潞安集团五阳煤矿位于山西省长治市襄垣县境内，矿区五阳铁路专线和太焦、邯长铁路线相接，交通十分便利。井田南北长平均约5.8km，东西长平均约8.8 km，井田面积为51.57km2，平均倾角9°，共两层煤分别为3号、15号煤，总厚约10m。井田工业储量为722Mt，可采储量560Mt，矿井服务年限为80 a。井田地质条件简单。矿井正常涌水量为120m3/h，最大涌水量为340 m3/h；煤层硬度系数f=2.3，煤质牌号为焦煤43；矿井瓦斯绝对涌出量9.143m3/min，相对瓦斯涌出量2.915 m3/t，为低瓦斯矿井，该矿井煤层有自燃倾向性，煤尘有爆炸性。

矿井采用立井两水平开拓，通风方式采用中央边界式。采煤方法为走向长壁综合机械化全部垮落法。煤炭运输采用钢丝绳芯胶带，辅助运输采用轨道运输。

矿井年工作日为300 d，每天净提升时间14h。矿井工作制度实行“三八”制。

专题部分题目是煤矸石的资源化利用。

关键词： 立井； 采区； 综合机械化长壁采煤法； 中央边界式

ABSTRACT

This design can be divided into two sections: general design and monographic study.

The general design is about a 5 Mt/a new underground mine design ofWuyang coal mine. It contains ten chapters: 1.overview and the geographical features of the mining field; 2.boundary and reserves of the mining field; 3.working system and designed mine capacity; 4.development of mining field; 5.preparation in mining area; 6.coal mining method; 7.underground conveying; 8.mine exaltation; 9.mine ventilation and safety technology; 10.the basic technical and economic index.

Wuyang coal mine of Lu’an Group lies in Xiangyuan County, Changzhi Municipality, Shanxi province. Wuyang railway of coal mine convergence Taijiao railway line and Hanchang railway line, the traffic is very convenient. It’s about 5.8 km along north-south direction and 8.8 km along the direction,with the 51.57 km2 total area. Two coal seams of this mine is 3and 15 with total thickness of 10 m and an average dip of 9°. The proved reserves of this coal mine are 722 Mt and the minable reserves are 560 Mt, with a mine life of 80 a.The geological condition of the mine is relatively simple. The normal mine inflow is 120 m3/h and the maximum mine inflow is 340 m3/h. It is bituminous coal 43. gas emission in absolute is 9.143m3／min and the relative volume of gas emission is 2.915 m3／t. It is a coal mine with low gas emission rate and coal spontaneous combustion tendency. And it’s a coal seam liable to dust explosion.

This mine adopts vertical shaft development with two mining level and exhaust ventilation, centralized juxtapose earlier and radial later. The adopted coal winning method is comprehensive mechanized in longwall mining with top-coal caving. The belt conveyor is applied to transport coal and rail transport is used in the auxiliary conveying.

We work 300 days per year ,and exaltate 14 hours one day .The “three–eight”working system is applied for coal mining .

The monographic study is the utilization of coal gangue.

Keywords： shaft ; mining area ; comprehensive mechanized in longwall mining ; trackless transport ; central-border
