张双楼矿5.0Mta新井设计.docx

1、 摘 要一般部分针对张双楼矿井进行了井型为1.8Mt/a的新井设计。张双楼矿井位于江苏省徐州市境内，井田走向长约9.52km，倾向长约3.27km，面积约32.06km2。主采煤层为9煤，平均倾角20，平均厚度5.8m。井田工业储量为267.74Mt，可采储量173.19Mt，矿井服务年限为74a。矿井正常涌水量为294m3/h，最大涌水量为453m3/h；矿井相对瓦斯涌出量为1.64m3/t，属低瓦斯矿井。根据井田地质条件，设计采用立井两水平（暗斜井延深）开拓方式，井田采用全采区式布置方式，共划分为十个采区，轨道大巷、运输大巷皆为岩石大巷，布置在9煤层底板岩层中。由于本矿井为低瓦斯矿井，故采

2、用中央并列式为主要通风方式，另掘西风井辅助通风。针对首采区西二采区采用了采区准备方式，采用两翼对角式开采，共分为11个区段，并进行了运煤、通风、运料、排矸、供电系统设计。针对9201工作面进行了采煤工艺设计。该工作面煤层平均厚度为5.6m，平均倾角19，直接顶为砂质泥岩，老顶为泥岩。工作面采用长壁综采放顶煤一次采全高采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“四六制”工作制度，截深0.8m，每天六个循环，循环进尺4.8m，月推进度144m。大巷采用胶带输送机运煤，辅助运输采用直流架线式电机车牵引固定箱式矿车。主井采用两套带平衡锤的12t箕斗提煤，副井采用多绳摩擦式提升机提升，装备一套标

3、准罐笼。专题部分题目为综采工作面的瓦斯涌出规律及瓦斯涌出量的预测，本文较系统的论述了煤层瓦斯的赋存状态与煤对瓦斯的吸附作用以及煤层瓦斯运移的基本规律，通过资料的收集、整理和分析，总结了综采工作面瓦斯浓度分布、采空区瓦斯流动及其浓度分布规律。翻译部分题目为Efficient mine microseismic monitoring，主要介绍了高效矿井微震监测方案的重要问题。关键词：张双楼矿井； 立井两水平； 采区布置； 综采放顶煤； 中央并列式； 软岩巷道； 瓦斯涌出规律； 瓦斯涌出量； 微震监测ABSTRACTThe general design is about a 1.80 Mt/a ne

4、w underground mine design of Zhangshuanglou coal mine. Zhangshuanglou coal mine is located in Xuzhou, JiangSu province. Its about 9.52 km on the strike and 3.27 km on the dip, with the 32.06 km2 total horizontal area. The minable coal seam is 9# with an average thickness of 5.8 m and an average dip

5、of 20. The proved reserves of this coal mine are 267.74 Mt and the minable reserves are 173.19 Mt, with a mine life of 74 a. The normal mine inflow is 294 m3/h and the maximum mine inflow is 453 m3/h. The mine gas emission rate is 1.64 m3/t which can be recognized as low gas mine.Based on the geolog

6、ical condition of the mine, this design uses a shaft two level(dark deep inclined shaft extension) development method, and full mining area preparation ,which divided into ten mining area, and track roadway and belt conveyor roadway are all rock roadways, arranged in the floor rock of 9# coal seam.

7、Taking into account of the low gas emission, mine main ventilation method use central listed ventilation.The design applies mining area preparation against the first band of West Two which divided into 11 section totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity

8、designing.The design conducted coal mining technology design against the 9201 face. The coal seam average thickness of this working face is 5.6 m and the average dip is 19, the immediate roof is sandy mudstone and the main roof is mudstone. The working face applies longwall top coal caving mining mi

9、ning method, and uses double drum shearer cutting coal which cuts twice each working cycle. Four-Six working system has been used in this design and the depth-web is 0.8 m with six working cycles per day, and the advance of a working cycle is 4.8 m and the advance is 144 m per month.Main roadway mak

10、es use of belt conveyor to transport coal resource, and DC overhead line electric locomotive traction fixed box-type tramcar to be assistant transport. The main shaft uses double 12t skips to lift coal with a balance hammer and the auxiliary shaft uses multirope friction hoist mention and a standard

11、 cage.The monographic study entitled Longwall Face Gas Emission Law and Gas Emission Prediction . This article discusses the basic law of the mode of occurrence of the coal seam gas adsorption of coal gas and coal seam gas migration and by data collection, collation and analysis, summed up the gas c
