毕业设计题目:超化煤矿0.9Mt/a 新井设计
毕业设计专题题目:西部脆弱矿区保水开采技术分析
摘 要
本设计包括三个部分:一般部分、专题部分和翻译部分。
一般部分为超化煤矿0.9Mt/a 新井设计。河南超 化煤矿位于河南郑州市境内,东有京
广铁路,北有豫04 公路,交通便利。井田走向长度约5.43km,倾向长度约2.5km,
面积约8.998 km2。主采煤层为二1 煤层,平均倾角为15°,平均厚度为7.5 m。井田工
业储量为92.46 Mt,可采储量为57.79 Mt,矿井服务年限为49 a。矿井正常涌水量为
500 m3/h,最大涌水量为650 m3/h。矿井绝对瓦斯涌出量为10.57 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:立井两水平开拓
上下山开采,立井直接延深;方案二:立井两水平开拓上下山开采,暗斜井延深;方
案三:立井两水平开拓上山开采,立井直接延深;方案四:立井两水平开拓上山开采,
暗斜井延深。通过技术经济比较,最终确定方案一为最优方案。一水平标高-200 m,
二水平标高-400m。
设计首采区采用采区准备方式,工作面长度120 m,采用综采放顶煤采煤法,矿
井年工作日为330 d,工作制度为“三八制”。
大巷采用胶带输送机运煤,辅助运输采用矿车运输。矿井通风方式为中央并列式。
专题部分题目是西部生态脆弱矿区保水开采技术分析,煤炭资源的开采为整个国
民经济持续稳定发展做出了重要的历史性贡献。我国西部是我国主要的产煤区,在西
部大开发的背景下,西部煤炭资源将得到大规模的开发。然而,煤炭资源的大规模开
发,不可避免地对自然生态状况产生极大的扰动,特别是对开采区域范围内的水文地
质环境产生极为明显的不可逆作用,从而严重破坏了地下水资源的自然赋存条件,使
本来就已经十分紧张的西部生态脆弱矿区水资源供需矛盾更加尖锐。在西部生态脆弱
矿区采取一定的保水开采技术是符合煤矿绿色开采技术的要求。
翻译部分题目是煤矿自动化和通信技术现状与发展趋势。

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 0.9 Mt/a new underground mine design of Chaohua coal
mine.Chaohua coal mine lies in Zhengzhou City, Henan province.As Jingguang railway
runs in the west of the mine field and NO.Yu04 Highway runs in the east of the mine field,
the traffic is convenient.It’s about 5.43 km on the strike and 2.5 km on the dip, with the
8.998 km2 total horizontal area.The minable coal seam is 21 with an average thickness of
7.5 m and an average dip of 15°.The proved reserves of this coal mine are 92.46 Mt and the
minable reserves are 57.79 Mt, with a mine life of 49 a. The normal mine inflow is 500
m3/h and the maximum mine inflow is 650 m3/h. The mine gas emission rate is 10.57
m3/min which belongs to low gas mine.
Based on the geological conditions of the mine, I bring forward four available projects
in technology.The first is vertical shaft development with two mining levels and the
extension of vertical shaft; the second is vertical shaft development with two mining levels
and the extension of blind inclined shaft; the third is vertical shaft development with two
mining levels and the extension of blind inclined shaft; the last is vertical shaft development
with two mining levels and the extension of vertical shaft. The second project is the best
comparing with other three projects in technology and economy.The first level is at -200
m.The second level is at -400 m.
Designed first mining district makes use of the method of the mining district
preparation.The length of working face is 120 m, which uses fully-mechanized coal caving
mining method. The working system is “three-eight” which produces 330 d/a.
Main roadway makes use of belt conveyor to transport coal resource, and mine car to
be assistant transport. the type of mine ventilation system is the central paratactic .
The monographic study is The analysis of fragile water mining technical in Western
mining ecological. The mining of coal resources for the entire national sustainable
economic development has made the important historic contribution. In western China is
the main regions in the development of western China, under the background of coal
resources, the west will get large-scale exploitation. However, the large-scale development
of coal resources, inevitably to natural ecological status greatly disturbed, especially in
mining area within the scope of the
The translated academic paper is Present situation and developing trend of coal mine
automationand communication technology.
