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。一般部分为司马矿300万t/a新井设计。司马煤矿位于山西省长治市，交通便利。井田走向长约6.61km，倾向长约6.36km，井田总面积为35km2。主采煤层为3号煤、9号煤，平均倾角为4，煤层平均总厚为8.08m。井田地质条件较为简单。井田工业储量为39089万t，矿井可采储量28253万t。矿井服务年限为62.8a，涌水量不大，矿井正常涌水量为120m3/h，最大涌水量为140m3/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：立井单水平开拓；方案二：主斜副立单水平开拓；方案三：立井两水平
2、开拓，立井直接延深；方案四：立井两水平开拓，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。水平标高+650 m。设计首采区采用采区准备方式，工作面长度240 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”。大巷采用胶带运输机运煤，辅助运输采用无轨胶轮车设备。矿井通风方式为两翼对角式通风。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-盘区巷道布置；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.矿井基本技术经济指标。专题部分题目是放顶煤冒放性影

4、t is a new design of Sima mine. Sima mine lines in ChangZhi in ShangXi province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 6.61km ,the width is about 6.36 km，well farmland total area is 352.The third is the main coal seam. The thickness of the mine
5、is about 8.08m in all. The proved reserves of the minefield are 390.89 million tons. The recoverable reserves are 282.53 million tons. The designed productive capacity is 3 million tons percent year, and the service life of the mine is 62.8 years. The normal flow of the mine is 120 m3 percent hour a
6、nd the max flow of the mine is 140 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.Based on the geological conditions of the mine, I bring forward four available projects in technology. The first is vertical shaft development with one mining level; the second is
7、 main slop and auxiliary shaft development ;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 first project is the best comparing with other
8、three projects in technology and economy.The level is at +650 m.Designed first mining district makes use of the method of the panel working.The length of working face is 240 m, which uses fully-mechanized coal caving mining method. The working system is “three-eight” which produces 330 d/a.Main road
9、way makes use of belt conveyor to transport coal resource, and Trackless Tyred Vehicle to be assistant transport. The type of mine ventilation system is two wings diagonal ventilation.This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.Th
10、e service 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 of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical
11、norms.Special subject parts of topics is Coal-rock movement law and drawing technolgy for fully mechanized caving face of thick coal seam.Translation part of main contentses is an analysis model concerning short-wall continuous mechanical mining, English topic is: Classification of conditions for sh
