1、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、设计生产能力及服务年限；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。一般部分为平煤二矿1.8Mt/a新井设计。平煤二矿位于河南省平顶山市，交通便利。井田走向长约4.9 km，倾向长约5.2 km，井田总面积为25.48km2。主采煤层为四21（戊10）煤，倾角317，平均8。煤层平均厚度为3.45 m。井田地质条件较为简单。井田工业储量为197.18Mt，矿井可采
2、储量159.32 Mt。矿井服务年限为63.2a，涌水量不大，矿井正常涌水量为548 m3/h，最大涌水量为1070 m3/h。矿井相对瓦斯涌出量为5.94 m3/t，为低瓦斯矿井。根据井田地质条件，提出四个技术上可行的开拓方案。方案一：立井单水平上下山（岩石大巷）；方案二：立井单水平上下山（煤层大巷）；方案三：立井两水平暗斜井延深（岩石大巷）；方案四：立井两水平暗斜井延深（煤层大巷）。通过粗略和详细技术经济比较，最终确定方案一为最优方案。一水平标高-430m，整个井田划分为2个带区和2个盘区。矿井采用中央并列式通风方式。矿井采用带区式准备方式，工作面设计长度200m，采用综合机械化一次采全高
3、采煤工艺。矿井年工作日为330d，昼夜净提升时间为16h。矿井采用“四六”制工作制度，三班生产，一班检修。循环进尺为0.6m，日产量为5402.7t。专题部分题目为浅析巷旁充填技术的研究与应用。翻译部分题目为Geotechnical considerations in mine backfilling in Australia。关键词：新井设计，立井，单水平，带区，中央并列式ABSTRACTThe three parts is included in this design,i.e.,the general part, special subject part and translation.
4、This general part 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 panels; 6. The method used in coal mining; 7. Transportation of the underground
5、; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.The general part is a new design of Pingdingshan mine with a production of 1.8 million t/a. Pingdingshan mine lines in Pingdengshan city, HeNan province. The traffic of roa
6、d and railway is very convenience to the mine. The run of the minefield is 4.9 km ,the width is about 5.2 km, well farmland total area is 25.25 km2. No. 4 are the main coal seam, and its dip angle is 217, 8 for average. The thickness of the mine are about 3.45 m. The geological conditions of the min
7、efield is relatively simple.The proved reserve of the minefield is 197.18 Mt. The designed productive capacity is159.32Mt, and the service life of the mine is 63.2years. The normal water flow of the mine is 548 m3/h and the max flow of the mine is 1070 m3/h. The relative gas emission rate of the min
8、eral well is 5.94 m3/t, for low gas mineral well.Based on the geological conditions of the mine, I bring forward four available project in technology. The first is vertical shaft development with one mining levels, the deep extension of blind slope; the second is vertical shaft development with two
9、mining levels; the third is vertical shaft development with one mining levels and the deep extension of blind slope,and the last is slope shaft development with two mining levels. The four project is the best comparing with other three projects in technology and economy. The first mining level is -4
10、30m. The mine field is divided into four strip districts and one mining district. Taking into account the long distance in the east and west direction, The type of mine ventilation is the centralized juxtapose ventilation.Designed first mining district makes use of the method of the mining district
11、preparation. The design length of working face is 200 m, which uses fully mechanized mining with full-seam mining technology. The working days in one year are 330. Everyday it takes 16 hours in lifting the coal. The operation mode in the mine is “four-six” with three teams mining and the other overh
12、auling. Every mining team makes three working cycle, and the overhauling team makes one working cycle. So everyday there are 6 working cycles. The advance of a working cycle is 0.6 m, and the quantity of 5402.7 ton coal is maked everyday.Special subject part of topics is: Analysis the study and appl
13、icatioon of roadside packing technology.The translated academic paper is: Geotechnical considerations in mine backfilling in Australia.Keywords:new mine design;vertical shaft;one mining levels of slope; strip district; centralized juxtapose ventilation. 目 录一般设计部分1 矿区概述及井田地质特征11.1矿区概述11.2井田地质特征21.3煤层
