煤电(集团)有限责任公司火烧铺井田新井设计—设计煤层:1#、3#、5#、7#、12#

 

摘   要
火烧铺矿井位于xx县特区西部,交通方便。矿区呈东南~西北向展布,为一七边形。全矿区走向长约为5.38Km,倾向长约为2.26 Km,井田面积12.16 km2。
矿井设计开采煤层为井田内的1#、3#、5#、7#、12#煤层,五层煤的平均厚度分别为1.46m、1.855m、1.49m、1.995、0.81m,煤层倾角从井田东翼到西翼变化,变化范围大致为17°~32°,煤层间距不大。井田内的工业储量约为8756.47万t,可采储量为6393.98万t。矿井设计年产量为90万t/a,设计服务年限为50.75a;日工作班数为四班,工作面作业方式采用 “三班采煤,一班准备”。井田存在着火7、火8、火23三条较大断层、特别是火23断层对井田地质构造影响较大,本矿井按煤与瓦斯突出矿井设计。
井田开拓方式为斜井开拓,设置主斜井、副斜井、回风斜井三条井筒。开采水平标高为+1620m。在整个井田内划分为两个阶段,四个采区,井下煤炭主要采用皮带运输机运输,材料和矸石等采用提升绞车和矿用电机车运输。
采煤方法为走向长壁后退式采煤法,回采工艺为综采。
矿井通风方式为中央并列式通风方式逐步过渡到分区抽出式通风方式,选用矿用隔爆对旋轴流抽出式通风机。

The new well design of HuoShaopu mine of Panjiang coal and electricity(Group) Co.Ltd.
               ——Design seam: 1#、3#、5#、7#、12#
Abstract
The HuoShaopu mine is located in the west of Pan country special area of LiuPanshui city,to the west of Fuyuan country, Yunnan Province, the road of Yunnan-Guizhou goes across the northern part of the Coal Mine,to the esat of east LiuGongtun of Pan country 44 kilometers, 382 kilometers away from Guiyang, 87 kilometers west to Nianyi, Kunming 266 kilometers, transportation is convenient. Mining area was the south-east to north-west -distribution for the 7-gon. The length for the whole mining area is 5.38Km, the tendency is about 2.26 Km, the mine has an area of 12.16 km2.
The design coal seams of exploitation for the mine are 1 #, 3 #, 5 #, 7 #, 12 #,   and the average thickness of five storeys were 1.46 m, 1885m, 1.49m, 1.995m, 0.81m,the coal inclination ranges from 17 °~32 ° from the east of the mine to the west of the mine, the coal seam space is not large. Mine industrial reserves is approximate 87,564,700t,recoverable reserves is 63,939,800t. The design capacity of mine is 900,000 t / a,the design length of service is 50.75a;  the number of work classes is four, face Operating form is "Three coal mining, then another preparation."There are three big faults (fire7,fire8,fire23) exist in the mine, particularly the fire23 fault has a big influence on the ming geological structure ,this mine design is  according to the coal and gas outburst mine .
The mine exploration way is inclined shaft, set up three shafts:the main inclined shaft,vice- inclined shaft,return wind inclined shaft. The elevation of mining level is the +1620 m. Within the entire mine is divided into two Stages, four mining area, the  under well transportion of coal is mainly by belt conveyor, hoist and motor vehicles for mine are used to transport the materials, waste rock and so on.
Mining method is the type of back to a long wall coal mining method, mining technology is fully mechanized mining.
Mine ventilation is the central ventilation ,then gradually transition to the district out of the way ventilation, selection of mining flameproof rotary axial out fan.
Key words: Mine development,Mining area division,Mining method,Ventilation
