丁集煤矿1.5Mt/a新井初步设计
摘要
本设计包括三个部分:一般部分、专题部分和翻译部分。
一般部分为丁集煤矿1.5 Mt/a新井设计。一般部分共包括10章:1.矿区概述及井田地质特征;2.井田境界和储量;3.矿井工作制度及设计生产能力、服务年限;4.井田开拓;5.准备方式-带区巷道布置;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。
丁集矿井位于安徽省淮南市西北部,距淮南市洞山约50km,行政区划隶属淮南市潘集区和凤台县境内。井田形状近似长方形,东西长约9.0 km,南北宽约8.0 km,面积约47.22 km2。井田内主采煤层为一层,为11-2#煤。煤层倾角平均7°,平均厚度3.5m。井田地质条件较为简单。
矿井工业储量为215.58Mt,可采储量为122.05Mt。矿井设计生产能力为1.5Mt/a。矿井服务年限62.6 a。矿井涌水量不大,正常涌水量为480 m3/h,最大涌水量为600 m3/h。矿井相对瓦斯涌出量为5.98 m3/t,属低瓦斯矿井。
矿井采用立井单水平开拓,采煤方法为倾斜长壁全部跨落一次采全高。全矿采用胶带运输机运煤,辅助运输采用矿车。矿井通风方式前期为中央并列式,后期根据需要在井田北翼增加一个区域风井。
矿井年工作日为330 d,日净提升时间16h,工作制度为“三八制”。
专题部分题目是煤矿开采冒落区注浆充填量预计研究。从冒落区注浆充填这种新的充填开采思路出发,通过研究冒落区顶板活动规律和冒落岩块碎胀系数变化规律,提出冒落区注浆量预计方法,为冒落区充填工程提供依据。
翻译部分是一篇关于神经网络程序在采矿工业中应用的,英文题目为Practical Neural Network Applications in the Mining Industry。

ABSTRACT
This design includes three parts: the general part, special subject part and translation part.
The general part is a new design of Dingji mine. This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.Development engineering of coalfield; 5.The layout of mining area; 6.The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.
Dingji mine locates at the northwest of Huainan City, 50km away from the Dongshan of Huainan City. The shape of minefield is like a rectangle which has a length of 9.0 km in the east and west direction while a width of 8.0 km in the south and north direction on average. The total area is Approximately 47.22 km2. The main coal seam in the mine is only one, which is the 11-2# coal seam. The average angle is 7 degree, while the thickness is about 3.5 m. The minefield geological condition is simple.
The proved reserves of the minefield are 215.58million tons. The recoverable reserves are 122.05 million tons. The designed productive capacity is 1.5 million tons per year. The service life is 62.6 years. The normal flow of the mine is480 m3 per hour and the max flow of the mine is 600 m3 per hour. The Relative gas discharge quantity is 5.98 m3 per ton. Thus it is Low gaseous mine.
The development of the mine is single level with a main inclined shaft and an auxiliary vertical shaft. the use of mines, coal mining way to the wall falls down is all over again by all. use adhesive tape zenko the coals to transport the tramcar. the ventilation the way for the central compound, late of the needs of double landownership in the north flank in a region of the wells.
The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”.
The title of the special subject part is “The theoretical research on the prediction of grout amount in backfill of collapse zone in coal mining”. A prediction method of grout amount in collapse zone is put forward by studying the regularity of the virgin roof movement and rock crack-expansion in the collapse zone, which provides a basis for the backfill project in collapse zone.
The translated academic paper is about neural network applications in the mining industry. Its title is “Practical Neural Network Applications in the Mining Industry”.
Keywords: vettical ; The levels of the mining;belt area ;The long arm of the coal mining; overhead line electric locomotive transport; centralized juxtapose ventilation
