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t/a新井设计。矿位于交通便利井田走向()长约,倾向()长约,井田总面积2。主采煤层为煤,倾角°,°。煤层平均厚为m。井田地质条件较为简单井田工业储量为t,矿井可采储量t。矿井服务年限为a,涌水量不大,矿井正常涌水量为m3/h,最大涌水量为m3/h。矿井瓦斯涌出量,为瓦斯矿井。
井田为开拓。大巷采用胶带运输机运煤,辅助运输采。矿井通风方式为通风。
矿井年工作日为30 d,工作制度为“”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.矿井工作制度设计生产能力服务年限4.井田开拓5.准备方式——6.采煤方法7.井下运输8.矿井提升9.矿井通风与安全10.矿井技术经济指标。专题部分题目翻译部分为ABSTRACT
The three parts is included in this design,i.e.,the general part, special subject part and translation.
The general part is a new design of QiDong mine with a production of 1.2 million t/a. QiDong mine lines in the southeast of SuZhou County, AnHui province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 9.2 km ,the width is about 5.0 km, well farmland total area is 35.4 km2. No. 61 is the main coal seam, and its dip angle is 10~15°, 14° for average. The thickness of the mine is about 3.6m respectively. The geological conditions of the minefield is relatively simple.
The proved reserve of the minefield is 122.02 Mt. The recoverable reserve is 98.6 Mt. The designed productive capacity is 1.2 Mt/a, and the service life of the mine is 63.21 years. The normal water flow of the mine is 234 m3/h and the max flow of the mine is 360 m3/h. The relative gas emission rate of the mineral well is 12.76 m3/t, for high gas mineral well.
The well farmland is a double-level with a shaft to expand. The coal is transported by the belt conveyer in the main roadway and 1 t mine car is used as the auxiliary transportation equipment. The way of mine ventilation is two wing opposite angle type.
The working system “three-eight” is used in Qidong mine. It produces 330d/a.
This general part includes te
