一般部分为张双楼煤矿300万t新井设计,共分10章:1.矿区概述及井田地质特征;2.井田境界和储量;3.矿井工作制度、设计生产能力及服务年限;4.井田开拓;5.准备方式-采区巷道布置;6.采煤方法;7.井下运输;8.矿井提升;9.矿井通风与安全技术;10.矿井基本技术经济指标。
张双楼煤矿位于江苏省徐州市沛县安国镇,交通便利。井田走向长度为8.2 km,倾斜长度3.8~4.0 km,。水平面积31.93 km2,倾斜面积32.29 km2。井田内主采煤层一层,即7#煤层,平均倾角8.6°,煤层平均厚9.5 m,井田工业储量为35447万t,可采储量24584万t,矿井服务年限为71.56 a。煤层硬度系数f=2.3,煤质牌号为气煤~肥煤。本矿井为低瓦斯矿井,瓦斯绝对涌出量为3.73 m3/min,CO2绝对涌出量为26.21 m3/min。矿区综采,机掘的最大最小煤尘浓度和平均浓度为337.8 mg/m3,136.8 mg/m3;35.4 mg/m3,16.2 mg/m3,煤尘爆炸性指数在43%左右,均属于有煤尘爆炸危险性煤层。区内山西组7#煤为不易自燃煤层矿井为Ⅲ级发火矿井,井田内的煤层自燃发火期一般为3—6月。矿井采用双立井两水平开拓,前期采用中央并列式通风,后期采用两翼对角式通风。一矿一面,采煤方法为长壁放顶煤全部垮落法。煤炭运输采用钢丝绳芯胶带,辅助运输采用电机车。
矿井年工作日为330 d,每天净提升时间16 h。矿井工作制度为:实行“三八”制。
专题部分题目是煤巷锚杆支护。
翻译部分是一篇关于煤柱设计的论文,英文原文题目为:THE EVOLUTION OF INTELLIGENT COAL PILLAR DESIGN: 1981-2006
关键词:新井设计;放顶煤;中央并列式
ABSTRACT
This design can be divided into three sections: general design, monographic study and translation of an academic paper.
The general design is about a 3 Mt/a new underground mine design of Zhangshuanglou coal mine. It contains ten chapters: 1.overview and the geographical features of the mining field; 2.boundary and reserves of the mining field; 3.working system, designed mine capacity and mine life; 4.development of mining field; 5.preparation in strip district; 6.coal mining method; 7.underground conveying; 8.mine exaltation; 9.mine ventilation and safety technology; 10.the basic technical and economic index.
Zhangshuanglou coal mine lies in Xuzhou, Jiangsu province.It is in Anguo town, the traffic is very convenient. It’s about 8.2 km on the strike and 3.9 km on the dip,with the 31.93 km2 total horizontal area. The minable coal seam of this mine is only 7 with an average thickness of 9.5 m and an average dip of 8.6°. The proved reserves of this coal mine are 354.47 Mt and the minable reserves are 245.84 Mt, with a mine life of 71.56 a.The geological condition of the mine is relatively simple. The absolute mine gas is 3.73m3/min,and the absolute carbon dioxide is 26.21 m3/min .The maximum and minimum coal dust density and average is 337.8 mg/m3,136.8 mg/m3;35.4 mg/m3,16.2 mg/m3.The normal mine inflow is120 m3/h and the maximum mine inflow is 142 m3/h. It is bituminous coal with low mine gas emission rate and coal spontaneous combustion tendency, and it’s a coal seam liable to dust explosion.
This mine adopts vertical shaft development with two mining level and exhaust ventilation, centralized juxtapose earlier and radial later. The adopted coal winning method is longwall mining on the dip with top-coal caving. The belt conveyor is applied to transport coal and motor vehicles is used in the auxiliary conveying.
We work 330 days per year ,and exaltate 16 hours one day .The “three–eight” working system is applied for coal mining .
The monographic study is Bolting for Coal Lane.
The translated academic paper is about coal pillar design .Its title is that the evolution of intelligent coal pillar desingn:1981-2006.
Keywords:the design of mine;top-coal caving ; centralized juxtapose ventilation
