岱庄煤矿1.2Mt/a新井设计
摘要
一般部分针对岱庄煤矿进行了井型为1.2 Mt/a的新井设计。岱庄煤矿位于山东省济宁市境内。煤层厚度平均2.9m，平均倾角都为3°。井田工业储量为160.23 Mt，可采储量124.5 Mt，矿井服务年限为79.8a。矿井正常涌水量为378 m3/h，最大涌水量为400 m3/h；矿井属低瓦斯矿井。
根据井田地质条件，设计采用立井单水平开拓方式，带区式布置方式，共划分为5个带区，水平标高-500 m。轨道大巷、胶带机大巷皆为岩石大巷，布置在煤层底板岩层中。
一带区共划分12个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。带区服务年限16年。
对工作面进行了采煤工艺设计。该工作面煤层平均厚度为2.9m，平均倾角3°，直接顶为粘土砂岩，老顶为细砂岩。工作面采用长壁综采一次采全高的采煤方法。采用双滚筒采煤机割煤，往返一次割两刀。采用“三八制”工作制度，截深0.8 m，每天六个循环，循环进尺4.8 m，月推进度144 m。
大巷采用胶带输送机运煤，辅助运输采用蓄电池式电机车牵引固定箱式矿车。主井采用两套带平衡锤的16 t箕斗提煤，副井采用一对1.5 t矿车双层四车宽罐笼运料和升降人员。
专题部分题目是《厚煤层分层开采及巷道合理位置确定模拟分析》，经过查阅大量资料和结合实验所得结论，认为本文所提出的确定厚煤层下分层煤层回采巷道合理位置的方法是可行的，研究结果对类似条件下巷道合理布置具有一定的指导意义。

ABSTRACT
The general design is about a 1.2Mt/a new underground mine design of Daizhuang coal mine. Daizhuang coal mine is located in Jining, Shandong province. The minable coal seam are 2.9m ，the average dip is 3°. The proved reserves of this coal mine are 311.4 Mt and the minable reserves are 124.5 Mt, with a mine life of79.8 a. The normal mine inflow is 378 m3/h and the maximum mine inflow is 400 m3/h. The mine can be recognized as low gas mine.
Based on the geological condition of the mine, this design uses vertical shaft single-level development method, both district and strip preparation ,which divided into 5 totally, The level is at -500 m .track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of coal seam. Taking into account of the high gas emission, mine ventilation method use central boundary ventilation in earlier stage and combined ventilation, excaves bottom gas drainage roadway before mining to relief gas pressure in advance.
The design apply strip preparation against the first band of One which divided into 12 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. It’s life is 16 a.
The design conducted coal mining technology design against the working face. The coal seam average thickness of this working face is 2.9 m and the average dip is 3°, the immediate roof is day sandstone and the main roof is sand stone. The working face apply fully-mechanized long-wall full-height coal caving method, and using double drum shearer cutting coal which cutting twice each working cycle. “Three-Eight” 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 working cycles is 4.8 m per day and 144 m per month.
Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses double 16 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins wide 1.5t four-car double-deck cage to lift material and personnel transportation.
Special section titled《Roadway seam slice mining and simulation analysis to determine a reasonable position》, having access to large amounts of data and binding experiments concluded that the determination of the proposed coal seam roadway under the tiered approach is reasonable and feasible location the findings of a similar arrangement under the roadway has some reasonable guidance.
