1、摘 要本设计说明书通过详细介绍山西同朔州平鲁区奥兴陶的井田概况和地质特征,经过一系列的方案论证比较,选择了适合本矿井的开拓方式、采煤方法和各生产系统。本设计为井田11#煤层的矿井设计,该煤层地质构造比较简单,平均厚度为4m,煤层倾角06o,属于近水平煤层,有煤尘爆炸危险。矿山工业储量为2550万t,可采储量为2300万t吨,设计生产能力为90万t/a,服务年限为26年。经过技术经济比较,选择了主斜井副斜井开拓方案,其中主、副井为斜井,回风井选择了立井。辅助运输系统与主运输系统相分离,其中辅助运输采用绞车牵引矿车方式,技术工艺简单,操作便利。矿井采用机械式抽出式通风系统。关键词:斜井开拓;盘区式
2、;一次采全高;中央式ABSTRACThis design specification describes the well field and geological characteristics of Auxingtao in Pinglu District, Luzhou City in Shanxi Province in detail. After a series of program comparisons and comparisons, the development method, coal mining method and various production syste
3、ms suitable for the mine are selected.This design is a well design for the 11# coal seam in the mine field. The coal seam has a simple geological structure with an average thickness of 4m and a coal seam tilt angle of 0 to 6o. It belongs to a nearly horizontal coal seam with the danger of coal dust
4、explosion. The industrial reserves of the mine are 25.5 million tons, the recoverable reserves are 2300 million tons, the designed production capacity is 900,000 tons, and the service life is 26 years.After the technical and economic comparison, the main inclined shaft, an auxiliary inclined well de
5、velopment scheme, was selected. The main and auxiliary wells were inclined wells, and the return wells selected vertical shafts. The auxiliary transportation system is separated from the main transportation system. The auxiliary transportation adopts a winch to pull the cart. The technology is simpl
