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。一般部分为孙村煤矿1.8Mt/a新井设计。共分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。孙村煤矿位于山东省泰山东侧的新泰市新汶办事处孙村镇境内,地处新汶煤田东部,位居山东新汶矿业集团公司腹地。井田走向长度为4.8km,倾斜长为6.88.4km,平均7.6km,井田水平宽度为6.68.7km,平均为7.3km,水平面积为41.6平方公里。主采煤层为2号煤和4号煤
2、,2号煤层平均厚度3.5m,4号煤层平均厚度2.8m,井田地质条件较简单。矿井工业储量为361Mt,可采储量270Mt。矿井正常涌水量为75m3/h,最大涌水量为180m3/h。矿井瓦斯涌出量低,为低瓦斯矿井。矿井为斜井多水平集中上下山开拓,大巷采用胶带输送机运煤,辅助运输采用电机车牵引矿车运输,矿井通风方式为对角式通风。一矿一面,矿井采用走向长壁综合机械化一次采全高开采法。矿井年工作日为330d,每天净提升时间16h。矿井工作制度采用“三八”制,两班生产、一班准备。专题部分题目是大采高开采和放顶煤开采的技术经济比较,主要是对厚煤层大采高综采和放顶煤综采的技术可行性和经济合理性进行了分析比较。
3、翻译部分主要内容为基于LSSVM的煤矿安全等级预报,英文题目为:Prediction of Coal Mine Safety Level Based on LSSVM。ABSTRACTThe 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 Suncun mine about 1.8Mt/a. This design includes ten chapters.
4、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. 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.
5、 9. The ventilation and the safety operation of the mine. 10. The basic economic and technical norms.Suncun mine located in east of TaiShan in Shandong Province. The run of the mine field is 4.8km,the width is about 7.6 km,mine farmland total area is 41.6 km 2. The number 2and 4 seam are the main co
6、al seams,The thickness of the two main coal is about 3.8m and 2.5m respectively. The coalfield geological condition is relativily simple.The proved reserves of the coalfield are 321 million tons. The recoverable reserves are 270 million tons. The normal flow of the mine is 75 m3 per hour and the max
7、 flow of the mine is 180 m3 per 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 adhesive tape transportation opporteunity coal.The working system “three-eight” is used in the Suncun mine. It produce
