1、華北科技學(xué)院畢業(yè)設(shè)計(jì)設(shè)計(jì)總說(shuō)明本設(shè)計(jì)包括兩部分:一般部分和專題部分。一般部分是河北開(kāi)灤集團(tuán)范各莊礦150萬(wàn)噸新井設(shè)計(jì)。全篇共有十篇,依次是:礦區(qū)概述及井田地質(zhì)特征,井田境界及儲(chǔ)量,礦井工作制度和設(shè)計(jì)生產(chǎn)能力,井田開(kāi)拓,采區(qū)巷道的布置,采煤方式,井下運(yùn)輸,礦井提升,礦井通風(fēng)與安全,礦井基本技術(shù)經(jīng)濟(jì)指標(biāo)。開(kāi)灤礦務(wù)局范各莊礦位于河北省唐山市古冶區(qū)境內(nèi),礦井井田走向5.73公里,傾向長(zhǎng)度為2.8公里。井田面積15.38平方公里。井田內(nèi)可采煤層共2層,分別為9號(hào)煤層和12號(hào)煤層,9號(hào)煤層為主采煤層,煤層賦存穩(wěn)定平
2、均厚度4.15米,平均傾角12度。井田內(nèi)工業(yè)儲(chǔ)量為1.98億噸,可采儲(chǔ)量為1.47億噸。相對(duì)瓦斯涌出量為0.12m3/t,絕對(duì)瓦斯涌出量為0.73m3/min,屬于低瓦斯礦井。煤層無(wú)自然發(fā)火現(xiàn)象。該礦井設(shè)計(jì)年生產(chǎn)能力為150萬(wàn)噸,服務(wù)年限為70年。采用雙立井兩水平開(kāi)拓采區(qū)開(kāi)采。開(kāi)采水平標(biāo)高為-475和-750兩個(gè)水平。礦井采用走向長(zhǎng)壁一次采全高全部垮落綜合機(jī)械化采煤法。礦井布置一個(gè)綜采面,工作面長(zhǎng)度為200米。煤的運(yùn)輸采用膠帶輸送機(jī)。礦井風(fēng)機(jī)工作方式為抽出式,礦井通風(fēng)方式為中央分列式通風(fēng)。專題部分為綜放
