1、摘要本設(shè)計(jì)礦井為雞西礦業(yè)集團(tuán)哈達(dá)煤礦1.5Mt/a新井設(shè)計(jì)。煤層工業(yè)牌號(hào)為1/3焦煤,可采儲(chǔ)量173.46Mt,服務(wù)年限為80a。井田走向長度6.75km,傾向長度4.25km,共有四層可采煤層,全區(qū)可采,即23#、30#、36#、37#煤層,賦存深度+25m~-800m,總厚度8.1m,平均傾角13.7,頂?shù)装宕蠖紴榉凵硯r,硬度較高。其中23#煤層與30#煤層間距135m、30#煤層與36#煤層間距40m、36#煤層與37#煤層間距25m,區(qū)內(nèi)有四條斷裂都為正斷層落差范圍在0~250m,將井田劃分為四個(gè)區(qū)域。設(shè)計(jì)礦井采用雙立井開拓,劃分三個(gè)水平。本設(shè)計(jì)為第一水平開拓
2、,采用梭式井底車場,集中大巷采區(qū)石門開拓布置,井底車場和集中大巷布置在23#煤層底板中,30#、36#、37#煤層采用聯(lián)合開采,在37#煤層底板中布置集中上山。大巷采用兩輛10t架線電機(jī)車牽引3t底卸式礦車運(yùn)輸。設(shè)計(jì)采區(qū)為中央采區(qū),走向長度2200m,傾斜長度1000m,煤層厚度2.5m傾角13.7。采用三條上山布置在煤層中,雙翼采區(qū)單翼回采,工作面長度190m,上行式通風(fēng)后退式回采,走向長壁采煤法,綜合機(jī)械化回采工藝一次采全高。通風(fēng)方式為兩翼對角式。關(guān)鍵詞可采儲(chǔ)量集中大巷采區(qū)石門走向長壁采煤法79AbstractThedesignofthemineforJiXiMi
