2、务年限为 67.8a， 涌水量不大，矿井正常涌水量为 263m3/h，最大涌水量为 447m3/h。矿井瓦斯涌出 量较低,为低瓦斯矿井。 井田为双立井两水平开拓。水平标高为0m、-250m，双立井开拓，主井装备 箕斗，副井装备罐笼。矿井通风方式为两翼对角式通风。 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-采区巷道布 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。 关键词：立井开拓 ；两翼对
3、角式 ；综采放顶煤 ；矿井通风 ABSTRACT This s a new design of DaYu mine with a production of 1.2Mt/a. DaYu mine lines in Northwest of Yuzhou in HeNan province. . The traffic of road and railway is very convenience to the mine. The run of the minefield is 3.9-4.2km ,the width is about 2.2km，well farmland total are
4、a is 8.7 2.The five is the main coal seam, and its dip angle is 13 degree. The thickness of the mine is about 10m in all. The proved reserves of the minefield are 121.6Mts. The recoverable reserves are 85.5Mts.The service life of the mine is 67.8 years. The normal flow of the mine is 263m3 percent h
5、our and the max flow of the mine is 447 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well. The well farmland is two level in shaft well to expand. The level should be located at the lever of 0m and -250m, which use raise and dip mining method of vertical shaft dev
6、elopment. The main shaft skip install skip and the auxiliary shaft install cage. The two wings opposite angles ventilation system is used in the mine. The working system “four-six” is used in the Dayu mine. It produced 330d/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.development engineering of coalfield; 5.The layout of banes; 6.The method used in
