文档介绍：摘要
本次设计任务为内蒙古自治区准格尔煤田东北隅小鱼沟煤矿8#煤层30万吨开采设计。,。近水平煤层,。
本设计年产量为30万吨,按年工作日330天计算,日产原煤909吨,服务年限为10年。井田开拓方式为斜井开拓。井田划分为南北两翼,盘区式划分,采用走向长壁一次采全高采煤方法开采,设计布置一个综采工作面和一个掘进工作面。
矿井主运输采用胶带机运输,辅助运输采用串车运输。通风系统为并列抽出式通风,掘进工作面通风方法为局扇压入式。
关键词:开拓系统采煤方法
Abstract
The design task to the northeastern corner of the fish coal mine in Inner Mongolia Autonomous Region, Jungar seam 30 million tons of mining design. Coal mine Ida the area , mining the average thickness of . Flat seam, recoverable reserves of million tons.
The designed annual output of 300,000 tons, annual working days 330 days, Nissan 909 tons of raw coal, the service life of 10 years. Ida to open up the way to open up for the inclined shaft. Ida is divided into northern and southern flanks, the panel-type division, mining Longwall mining overall mining method, the design layout of a fully mechanized coal face and a heading face.
Mine the main transport belt conveyor and auxiliary transport string of car transport. Pressure ventilation system for the parallel exhaust ventilation, heading face ventilation methods for the local fan-in.
Keywords: system development coal mining method
