2、5Mt。矿井正常涌水量为75m3/h，最大涌水量为120m3/h。矿井瓦斯涌出量高，为高瓦斯矿井。矿井为斜井单水平开拓，大巷采用胶带输送机运煤，辅助运输采用矿车，矿井通风方式为中央并列式通风。一矿一面，矿井采用倾斜长壁综合机械化放顶煤开采。矿井年工作日为330d，每天净提升时间14h。矿井工作制度采用“三八”制，两班生产、一班准备。专题部分题目是煤矿开采冒落区注浆充填量预计研究。主要是对当前国内采煤沉陷区生态修复做了分析。翻译部分主要内容为原位渗透性测量对建立地层岩石分层开采的影响，英文题目为：Practical Neural Network Applications in the Minin

3、g IndustryABSTRACTThe three parts are included in this design, i.e., the general part， special subject part and translated part.The general part is a new design of sangshuping. This design includes ten chapters. 1. An outline of the mine field geology. 2. Boundary and the reserves of mine. 3. The se

4、rvice life and working system of mine. 4. development engineering of coalfield. 5. The layout of panels. 6. The method used in coal mining. 7. Transportation of the underground. 8. The lifting system of the mine. 9. The ventilation and the safety operation of the mine. 10. The basic economic and tec

5、hnical norms.Sangshuping in coal mine because of hancheng mining district, to the west of the Yellow River is the northernmost town, is apart from the HanCheng straight from about for 35 km. Administrative districts belongs to sangshuping town of jurisdiction. The run of the mine field is 4.76.6 km，

6、the width is about 7.9 km，mine farmland total area is 28.5 km 2. The four nine and eleven is the main coal seam，The thickness of the three main coal is about 11.7m、12.5m and 3.3m respectively. The coalfield geological condition is simple.The proved reserves of the coalfield are 648.73 million tons.

7、The recoverable reserves are 440.75 million tons. The normal flow of the mine is 75 m3 percent hour and the max flow of the mine is 120m3 percent hour. The mineral gas gushes the deal lower，for low gas mineral mine.The mine farmland in an inclined mine to expand.The main transportation uses the adhe

8、sive tape transportation opporteunity coal.The working system “three-eight” is used in the Pingshuo No.3 mine. It produced 330d/a.The development of the mine is single level with a main inclined shaft and an auxiliary vertical shaft. The number of the working faces is only one. Comprehensive mechani

9、zation puts in the top coal technology is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mine cars. The ventilation type in the early stage is centralized juxtapose. In the late stage two air shafts

10、in the boundary should be driven. The ventilation method is extraction.The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”.目录第一章 矿区概述及井田地质特征- 1 -1.1矿区概述- 1 -1.1.1 矿区地理位置- 1 -1.1.2矿区地形、地貌- 1 -1.1.3 矿区气候条件- 2 -1.1.4 矿区的水文情
