摘 要
本设计包括三个部分:一般部分、专题部分和翻译部分。
一般部分是平煤二矿150万吨新井设计。全篇共分五章:矿井概述及井田地质特征、井田开拓、采煤方法及采区巷道布置、矿井通风与矿井安全技术措施。
平煤二矿位于河南省平顶山市。矿井总面积为10.68m2。主采煤层为己15、己17、庚20煤。厚度分别为3.5m,3.2m,5.7m。己15、己17煤层相距23.3m,己17、庚20煤层相距62.21m。煤层倾角平均为7度。矿井工业储量为181.47Mt,可采储量为137.92Mt。矿井设计年生产能力为1.5Mt,服务年限为66年。矿井正常涌水量为172.49m3/h。矿井瓦斯绝对涌出量为1.254 m3/min,此矿井为低瓦斯矿井。矿井采用“三?八”工作制。
矿井开拓方式为单水平开拓。主井采用箕斗提升,副井采用罐笼提升。采煤方法为走向长壁综合机械化开采,工作面长为188m。
矿井设置一个生产工作面和一个备用工作面。采用可伸缩式胶带输送机运煤,采用矿车运输物料等。矿井服务年限内采用中央分列式通风。
专题部分介绍了平煤二矿庚组煤开采地下水防治技术。
翻译部分题目为“The Features and Prevention of the Gas Pouring from the Breaking Coal-bed of the Comprehensively Mechanized Mining Face”,对综放工作面瓦斯涌出特点的进行了分析。

ABSTRACT
This design consists three parts: the general part, the special part and the translated part.
The general part is a new design for Pingmei Er colliery, and its throughput is 1.5Mt per year. It contains ten chapters: summarize of the mine field geological character, the mine boundary and reserves, designing throughput、labor system and serving years of the mine, mining field deploitation, the preparing manners, disposal of laneway in mining area , the excavating coal method,transportation of underground, mine lifting and transportation, mine ventilation and safety, and the economic and technologic index of the mine.
The Pingmei Er colliery located in Pingdingshan, Henan Province. The total area of the mine is 11.6 km2. The main exploitation coal seams are 15#, 17# and 20#. The thickness of 15# coal is 3.5 meters; 17# coal is 3.2 meters;20# coal is 5.7meters. The distance between 17# and 15# coal seams is 23.3meters,17# and 15# coal seams is 62.21meters. The average obliquity of the coal seams is 7 degrees. The industry reserves of the mine field are 189.9 Mt and the accessible reserves of the minefield are 144.37Mt. The design production capacity is 1500 Kt per year. The service life is 69 years. The normal effusing water of mine is 172.49m3/h on average. The comparative effusing of gas is 1.254 m3/min, so it is a low gassy mine.the 15# and 17# coal seams has no spontaneous combustion tendency.
The labor system of the mine is “three-eight".
The deploitation manner is shafts with one levels .The main shaft uses skip hoisting and the auxiliary shaft adopts cage hoisting. The mining method of the mine is fully-mechanized face with longwall in the strike; the length of the longwall face is 188 m.
There is one working face in the mine, and the other is for preparation. Flexible belt conveyor is used in the coal transportation. The materials and refuse are transported by tramcars tons in the ancillary transportation. The method of mine ventilation in this shift is Central march-past ventilation throughout the severice life.
The special part mainly introduces THE KEY TECHNIQUE IN INPROVEING SHAFT HOISTING CAPACITY FOR LARGE COAL MINE. .
The translation part mainly introduces theory and application of safety monitor mystem about SUDDEN ROCK FAILURES IN MINING COAL SEAMS OF THE KIZEL BASIN”
Keywords: industry reserve, vertical shaft development, labor system, mining method, fully-mechanized face with longwall in the strike,method of mine ventilation
