陈四楼煤矿1.5Mta新井设计.docx

1、摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为陈四楼1.5 Mt/a新井设计。陈四楼煤矿位于河南省永城市西北郊区，交通较为便利。井田倾向（东西）长约4.40 km，走向（南北）长约8.7km，井田总面积约为34.2 km2。主采煤层为二2号煤层，平均倾角为10，煤层平均厚度为3.25 m。井田工业储量为160.66Mt，矿井可采储量115.67 Mt 。该矿井服务年限为59.32 a，涌水量不大，矿井正常涌水量为894 m3/h，最大涌水量为1200 m3/h。矿井瓦斯涌出量较低，为低瓦斯矿井。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：立井单水平加暗斜井开拓；

2、方案二：立井单水平上下山开拓；方案三：立井两水平开拓（运输大巷布置在岩层中，立井直接延深）；方案四：立井两水平开拓（运输大巷布置在煤层中，立井直接延深）。通过技术经济比较，最终确定方案三为最优方案。一水平标高-540 m，二水平标高-760 m。井田为立井两水平开拓；综采一次采全高采煤法；矿井通风方式为两翼对角式。矿井年工作日为330d，工作制度为“四六”制。一般部分共包括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、服务年限；4.井田开拓；5.准备方式-带区巷道布置；6.采煤方法；7.井下运输；8.矿井提升；9.矿井通风与安全技术；10.矿井基本技术

3、经济指标。专题部分的题目为浅析煤层开采对地面桥梁的影响，主要针阐述了地表变形和对桥梁结构的影响，进而从煤层开采方面提出了一些解决措施。翻译的内容为液压支架的静力分析和模态分析，英文题目为：The Structure Statics Analysis and Transient Dynamics Analysis of Hydraulic Support关键词：陈四楼煤矿； 立井； 带区布置； 综采一次采全高采煤法； 两翼对角式 ABSTRACTThis design includes of three parts: the general part, special subject part

4、and translated part. The general part is a new design of Chensilou mine. Chensilou mine lines in north-west of Yongcheng in Henan province. The traffic of road and railway is convenience to the mine. The width of the minefield is 4.40 km ,the width is about 8.70 km，well farmland total area is 34.20k

5、m2.The two is the main coal seam, and its average dip angle is 10degree. The thickness of the mine is about 3.25 m in all. The proved reserves of the minefield are 206.49 Mt. The recoverable reserves are 125.13 Mt. The designed productive capacity is 1.5 Mt percent year, and the service life of the

6、mine is 64.17 years. The normal flow of the mine is 894 m3 percent hour and the max flow of the mine is 1200 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.Mine geological conditions under the proposed development schemes for the four technically feasible. Opti

7、on One: Single-level plus dark inclined shaft development; Option Two: One level down the open shaft; Option Three: Vertical two-level development (transport arranged in rocks in the roadway, a direct extension shaft deep); program four: two horizontal shaft development (Transportation Roadway layou

8、t in coal, direct extension shaft deep). Through technical and economic comparison, the final three as the best program to determine the program. A level elevation of -650 m, -850 m elevation of the second levelMine shaft of two levels to explore; fully mechanized mining overall high-mining method;

9、mine ventilation for the two wings on the diagonal. The working system “four-six” is used in the Chensilou mine. It produced 330 d/a.This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.develo
