摘要
。翟镇煤矿位于山东省泰安市管辖的新泰市境内,交通便利。井田走向(东西),倾向(南北),。主采煤层为4#、6#煤,煤层倾角为5~15,。井田地质条件较为简单。
井田工业储量为10979万t,可采储量为7875万t。。,涌水量不大,矿井正常涌水量为250m3/h,最大涌水量为400m3/h。 m3/t,,为低瓦斯矿井。
井田开拓方式为立井单水平上下山开拓。采用胶带输送机运煤,采用矿车进行辅助运输。矿井通风方式为中央并列式通风。矿井年工作日为330d,工作制度为“三八”制。
一般部分共包括9章:1、矿区概述与地质特征;2、井田境界和储量;3、矿井工作制度、设计生产能力及服务年限;4、井田开拓;5、准备方式——带区巷道布置;6、采煤方法; 7、井下运输;8、矿井提升;9、矿井通风与安全;
关键词:立井;单水平;带区;中央并列式通风
ABSTRACT
The general part is a new design for Zhaizhen mine. Zhaizhen mine is located in Xintai es within the jurisdiction of Tai’an in Shandong province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is ,the width is about 3km,and the total area is fourth and the sixth are the main coal seams, and its dip angle is 5~15 degree. The thickness of the mine is about in all. The geologic structure of this coalfield is simple.
The recoverable reserves of the coalfield are million tons,and the minable reserves are million tons. The designed productive capacity is million tons percent year, and the service life of the mine is years. The normal flow of the mine is 250m3 per hour and the max flow of the mine is 400 m3 per hour. The relative mine gas gush is m3/t and the absolute gush is m3/min, so it is a low gas mine.
The mine is a single level in two shafts to develop. Te central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the ventilation mode of this mine is center juxtapose form.
The “three-eight” working system is used in the Zhaizhen mine. It produces for 330 days a year. This design includes ten chapters: outline of the mine field geology; and the reserves of mine; service life and working system
