经坊煤矿配采井田开拓及采区布置设计

摘要

针对经坊煤矿3号煤层原煤灰分、硫份相对较低,发热量相对较高的煤质特征,为充分利用资源、提高煤矿经济效益,对经坊煤矿的3、9号煤层进行了配采设计.文章分析了经坊煤矿的井田自然概况及矿井生产现状,重点介绍了3、9号煤层的井田开拓方案的设计与配采方案的确定,详细介绍了采区主要装备:采煤机、刮板输送机、转载机、破碎机、带式输送机以及液压支架的选型.该配采设计方案可为相类似矿井提供借鉴.%Aiming at the low ash and sulfur content,and high calorific value of raw coal in Jingfang Mine No.3 coal seam,in order to make full of coal resources and improve the economic benefit of coal mine,a apportion mining scheme was designed for the No.3 and No.9 coal seam.The natural conditions and coal mine production situation were analyzed,determination method of the mining filed development design and mining scheme of No.3 and No.9 seams were introduced,the selection of main mining equipment was detailed,including shearer,scraper conveyor,reversed loader,crusher,belt conveyor and selection of hydraulic support.
