田陈煤矿1.2Mta新井设计【专题冲击矿压及其防治措施】.docx

1、摘 要本设计包括三个部分：一般设计部分、专题设计部分和翻译部分。一般部分为田陈矿1.2Mt/a的新井设计。田陈煤矿位于山东省滕州市境内，交通十分便利。井田走向（东西）长平均约7.1km，倾向（南北）长平均约3.7km，井田水平面积为26km2。主采煤层一层，即3上煤层，平均倾角10，厚约4.0 m。井田工业储量为137.13Mt，可采储量104.37Mt，矿井服务年限为65.4a。井田地质条件简单。表土层平均厚度55m；矿井正常涌水量为393m3/h，最大涌水量为620 m3/h；煤层硬度系数f=1.7，煤质牌号为气煤45；矿井绝对瓦斯涌出量为0.77 m3/min，属低瓦斯矿井；煤层有自燃发

2、火倾向，发火期36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。方案一：立井两水平开采，立井直接延深至-700 m水平；方案二：立井两水平开采，暗斜井延深至-700 m水平；方案三：主斜副立两水平开采，暗斜井延伸至-700m水平；方案四：主斜副立两水平开采，暗立井井延伸至-700m水平。通过技术经济比较，最终确定方案二为最优方案。将主采煤层划分为两个水平，一水平标高-550 m，二水平标高-700 m，井田走向大断层将井田分为南北两部分。设计首采区采用带区准备方式，工作面长度170m，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

3、修。生产班每班3个循环，日进6个循环，循环进尺0.8 m，日产量4341.12t。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9t双箕斗带平衡锤提煤，副井装备一对3 t矿车双层单车罐笼带平衡锤担负辅助运输任务。矿井采用中央并列式通风。通风容易时期矿井总需风量6056.6 m3/min，矿井通风总阻力1322Pa，风阻0.1Ns2/m8，等积孔3.15m2，矿井通风容易。矿井通风困难时期矿井总风量6536.4 m3/min，矿井通风总阻力1779.1Pa，风阻0.159 Ns2/m8，等积孔2.87m2，矿井通风容易。专题部分题目是冲击矿压及其预防控制。翻译部分是一篇

4、关于煤矿开采中的软岩优化工程的论文，英文原文题目为：Optimization of soft rock engineering with particular reference to coal mining关键词：立井；上下山开采；大采高；沿空掘巷；中央并列式；冲击矿压ABSTRACTThis design can be divided into three sections: general design, monographic study and translation of an academic paper.The general design is about a 1.2 Mt/

5、a new underground mine design of Tianchen coal mine. Tianchen coal mine lies in Tenggzhou, Shandong province. , the traffic is very convenient. Its about 7.1 km on the strike and 3.7 km on the dip,with the 26.00km2 total horizontal area. The minable coal seam of this mine is only 3上 with an average

6、thickness of 4.0 m and an average dip of 10. The proved reserves of this coal mine are 137.13 Mt and the minable reserves are 104.37 Mt, with a mine life of 65.4 a.The geological condition of the mine is relatively simple. The normal mine inflow is 393 m3/h and the maximum mine inflow is 620 m3/h. I

7、t is bituminous coal 45 with low mine gas emission rate and coal spontaneous combustion tendency, and its a coal seam liable to explosion.Based on the geological condition of the mine, I bring forward four available project in technology. The first is vertical shaft development with two mining level

8、s and the extension of inclined shaft go to -700 m; thr second is vertical shaft development with two mining levels and the extension of vertical shaft go to -700 m; the third is vertical shaft development with two mining levels and the extension of inclined shaft go to -820 m; the last is vertical

9、shaft development with two mining levels and the extension of vertical shaft go to -820 m. The secend project is the best comparing with other three project in technology and economy. The first level is at -450 m, The second level is at -700 m, Because a major fault lies in the center of mine field,

10、 the mine field is divided into the north section and the south section.Designed first mining district makes use of the method of preparation in mining area, the length of working face is 223 m, which uses fully-mechanized coal mining technology, and fully caving method to deal with goaf. The workin

11、g 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 0.6 m, and quantity of 5432.16 ton coal is makedeveryday.Main roadway makes use of belt conveyor to transport coal res

12、ource, 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 o

13、f areas ventilation method. At the easy time of mine ventilation, the total air quantity is 6056.6 m3 per minute, the total mine ventilation resistance is 1322 Pa, the coefficient of resistance is 0.100Ns2/m8, equivalent orifice is 3.15 m2. At the difficult time of mine ventilation, the total air qu

14、antity is6536.4 about m3 per minute, the total mine ventilation resistance is 1779.1 Pa, the coefficient of resistance is 0.159 Ns2/m8, equivalent orifice is 2.87 m2.
