范各庄矿150万吨新井设计
设计总说明
本设计包括两部分:一般部分和专题部分。
一般部分是河北开滦集团范各庄矿150万吨新井设计。全篇共有十篇,依次是:矿区概述及井田地质特征,井田境界及储量,矿井工作制度和设计生产能力,井田开拓,采区巷道的布置,采煤方式,井下运输,矿井提升,矿井通风与安全,矿井基本技术经济指标。
开滦矿务局范各庄矿位于河北省唐山市古冶区境内,,。。井田内可采煤层共2层,分别为9号煤层和12号煤层,9号煤层为主采煤层,,平均倾角12度。,。 m3/t,,属于低瓦斯矿井。煤层无自然发火现象。
该矿井设计年生产能力为150万吨,服务年限为70年。采用双立井两水平开拓采区开采。开采水平标高为-475和-750两个水平。矿井采用走向长壁一次采全高全部垮落综合机械化采煤法。
矿井布置一个综采面,工作面长度为200米。煤的运输采用胶带输送机。矿井风机工作方式为抽出式,矿井通风方式为中央分列式通风。
专题部分为综放工作面采空区自然发火的规律及防治
关键词:井田开拓;采煤方式;通风安全;综合机械化
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 low-gas coal mine. Seam-free bustion phenomenon.
The designed annual production capacity of the mine million tons, length of service for 70 years. Two-level dual-shaft 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
