许瞳矿1.5Mta新井设计.docx

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。一般部分为许疃煤矿1.5Mt/a新井设计。许疃矿位于安徽省宿州市西南部，地处蒙城县板桥镇境内，区内交通十分便利。井田东西走向长7km，南北倾向宽23km，井田面积约20km2。井田内可采煤层共有10层，主采煤层为72煤。井田内72煤倾角在314之间，平均厚度3m。矿井工业储量为348.46Mt，可采储量为281.56Mt，设计服务年限134.1a。矿井正常涌水量为550m3/h，最大涌水量为660m3/h。矿井相对瓦斯涌出量为12m3/t，绝对瓦斯涌出量为37.9m3/min，属高瓦斯矿井。煤层无自燃发火倾向，但煤尘有爆炸危险性。根据井田

2、地质条件，提出四个技术上可行的开拓方案。方案一:立井单水平开拓，中央并列式通风。方案二：立井单水平开拓，两翼对角式通风，即风井布置在井田南北翼边界。方案三：立井两水平上山式开拓，立井延伸。方案四：立井两水平暗斜井延伸式开拓。通过粗略和详细技术经济比较，最终确定方案二为最优方案。水平标高-600m。整个井田划分为7个带区和2个采区。矿井采用带区式准备方式，工作面设计长度220m，采用综合机械化一次采全高采煤工艺。矿井年工作日为330d，昼夜净提升时间为16h。矿井采用“三八”制工作制度，两班生产，一班检修。生产班每班进4刀。循环进尺为0.6m，日产量为4243.54t。矿井煤炭采用胶带输送机运输

3、，辅助运输采用蓄电池式电机车牵引固定箱式矿车。主井采用两对16t底卸式箕斗提煤，副井采用一对1.5t矿车双层四车加宽罐笼运送物料和升降人员。专题部分题目为：深部煤与瓦斯共采技术浅析。主要介绍了瓦斯抽采的理论和我国抽采瓦斯的主要技术方法。翻译部分主要内容是关于解决矿井运输系统问题的模型，英文题目为：OPERATIONS MODELING AND ANALYSIS OF AN UNDERGROUND COAL MINE。关键词：立井；单水平；带区；综合机械化一次采全高；两翼对角式通风第VIII页ABSTRACTThis design includes three parts: the genera

4、l design, the monographic study and the translation.The general design is about a 1.5Mt/a new underground mine design of Xutuan Coal Mine. Xutuan Coal Mine lies in the west of Suzhou City, Anhui province. The transportation in the mining area is very convenient. Its about 7 km on the strike and 34 k

5、m on the dip, with the 20 km2 total area. There are 10 minable coal seam. The main aquifer coal seam is 72 coal seam with an average thickness of 3 m, and the dip of 72 coal seam is 314. The proved reserves of this coal mine are 348.46 Mt and the minable reserves are 281.56 Mt, with a mine life of 1

6、34.1 a. The normal mine inflow is 550 m3/h and the maximum mine inflow is 660 m3/h. The mine relative gas emission quantity is 12m3/t, and the absolute gas emission quantity is 37.9m3/min. Thus, it is a high gas mine. The coal seam has no spontaneous combustion tendency, but the coal dust has explos

7、ion hazard.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 type of mine ventilation is the centralized juxtapose ventilation; the second is vertical shaft development with one mi

8、ning levels, The type of mine ventilation is two wings diagonal ventilation; the third is vertical shaft development with two mining levels, the deep extension of shaft, and an auxiliary level is set on the east wing, and the last is vertical shaft development with two mining levels, the deep extens

9、ion of blind slope. The first project is the best comparing with other three projects in technology and economy. The mining level is -600m. The mine field is divided into seven strip districts and two mining district. Designed first mining district makes use of the method of the mining district prep

10、aration. The design length of working face is 220 m, which uses fully mechanized mining the full-height 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 “three-eight” with two teams mining and the other overhauling. E

11、very mining team makes into four knife. The advance of a working cycle is 0.6 m, and the quantity of 4243.54 ton coal is maked everyday.Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. The main shaft uses two double 16 t skips to lift coal a

12、nd the auxiliary shaft uses a twins wide 1 t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled “Deep coal and gas extraction Technical Analysis”. The study Mainly simple gas extraction theory and Chinas CMM techniques.The translated academic paper

13、 is about solving the problem of mine transport systems model.
