華北科技學(xué)院畢業(yè) 設(shè)計 設(shè)計總說明 本設(shè)計包括兩部分:一般部分和專題部分。 一般部分是河北開灤集團范各莊礦 150萬噸新井設(shè)計。全篇共有十篇,依次是:礦區(qū)概述及井田地質(zhì)特征,井田境界及儲量,礦井工作制度和設(shè)計生產(chǎn)能力,井田開拓,采區(qū) 巷道的布置,采煤方式,井下運輸,礦井提升,礦井通風(fēng)與安全 ,礦井基本技術(shù)經(jīng)濟指標(biāo) 。 開灤礦務(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 ,傾向長度為 。井田面積 。井田內(nèi)可采煤層共 2層,分別為 9號煤層和 12號煤層, 9號煤層為主采煤層,煤層賦存穩(wěn)定平均厚度 ,平均傾角 12度。井田內(nèi)工業(yè)儲量為 ,可采儲量為 。相對瓦斯涌出量為 m3/t,絕對瓦斯涌出量為 ,屬于低瓦斯礦井。煤層無自然發(fā)火現(xiàn)象。 該礦井設(shè)計年生產(chǎn)能力為 150萬噸,服務(wù)年限為 70年。采用雙立 井兩 水平開拓 采區(qū)開采。開采水平標(biāo)高為 475和 750兩個水平。礦井采用 走向 長壁 一次采全高全部垮落 綜合機械化采煤法。 礦井布置 一 個綜采面,工作面長度為 200米。煤的運輸采用膠帶輸送機。礦井風(fēng)機工作方式為抽出式,礦井通風(fēng)方式 為中央分列式通風(fēng) 。 專題部分為 綜放工作面采空區(qū) 自然發(fā)火的規(guī)律及防治 關(guān)鍵詞 :井田開拓; 采煤方式 ; 通風(fēng)安全;綜合機械化 華北科技學(xué)院畢業(yè)設(shè)計 The Brief Introduction of the Design The design includes two parts: a general part and special part. The general part of the Group of Hebei Kailuan Fangezhuang mine million tons of new wells design. A total of 10 full papers, were: an overview of mining and mine geology, mine level and reserves, mine production capacity and design of work systems, mine development, with the layout of roadway, mining methods, underground transport, mine hoist, mine ventilation and security. Bureau of Mines Fangezhuang Kailuan mine is located in Tangshan City, Hebei Province guye district territory to mine Waida kilometers, inclined to a length of kilometers. Mine area of square kilometers. Mine coal seam with a 2 layer, respectively, on the 9th and the 12th coal seam, the main coal seam No. 9 coal seam, coal storage stability of the average thickness of meters, with an average inclination of 12 degrees. Mine industrial reserves of 198 million tons, recoverable reserves of 147 million tons. Gas emission relative to m3 / t, the absolute amount of gas emission , a lowgas coal mine. Seamfree spontaneous bustion phenomenon. The designed annual production capacity of the mine million tons, length of service for 70 years. Twolevel dualshaft mining area to open up mining. Mining the level of elevation for the two levels of 475 and 750. Mine used to take a long time the entire wall falling all integrated highmechanized coal mining law. Mine layout of a fully mechanized coal mining face, face length of 200 meters. The use of coal belt conveyor transport. Mine fans for taking the type of work, ventilation points out for the central ventilation. Thematic part of topcoal caving face goaf spontaneous bustion of the Regulation and Control Key words: Mine development。 mining。 ventilation security。 prehensive mechanization華北科技學(xué)院畢業(yè)設(shè)計一般部分 1 目 錄 設(shè)計總說明 ..............................................................................................................................
