陈四楼矿井1.2Mta新井设计.doc

1、摘 要一般部分针对陈四楼矿井进行了井型为1.2 Mt/a的新井设计。顾桥矿井位于河南省永城市境内，井田走向长约6.5 km，倾向长约3.79km，面积约24.69km2。主采煤层为二2煤层，平均厚度为3.54 m，平均倾角都为9.73。井田工业储量为126.88 Mt，可采储量87.11 Mt，矿井服务年限为55.8 a。矿井正常涌水量为894 m3/h，最大涌水量为1200 m3/h；矿井相对瓦斯涌出量为1.0 m3/t，属低瓦斯、大涌水矿井。根据井田地质条件，设计采用立井两水平开拓方式，采区带区式布置方式，共划分为3个带区，5个采区，第一水平标高-540 m，第二水平标高-900m。轨道大

2、巷、运输大巷和回风大巷皆为岩石大巷，布置在二2煤层底板岩层中。针对一带区进行了准备方式设计。共划分10个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。第一条带服务时间为15个月。对2106工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.54m，平均倾角8，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，每天五个循环，循环进尺4.0 m，月推进度120 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12 t箕斗提煤，副井采用一对1.

3、0 t矿车双层四车宽罐笼运料和升降人员。专题部分题目是Discussion of the drainage of the gas，该文系统总结评述了近年来煤矿瓦斯治理和抽放理论及其应用的诸多成果和最新进展，指出覆岩采动裂隙的分布形态及其中瓦斯运移规律是今后的研究重点，也是实现煤与瓦斯安全共采的理论基础。翻译部分题目为Optimization model of Coal Mine roadway layout system Based on Evidence Theory and Its Application，该解算方法与其它解算方法不同的是本法以风网的风量和扇风机工况点作为解算网路的基础数据

4、，对生产矿井的通风网路解算更能显示其优越性。关键词：陈四楼矿；立井两水平；带区布置；综采大采高；大涌水；瓦斯抽放ABSTRACTThe general design is about a 1.2Mt/a new underground mine design of Chensilou coal mine. Chensilou coal mine is located in YongCheng, HeNan province. Its about 6.5 km on the strike and 3.79 km on the dip, with the 24.69 km2 total horiz

5、ontal area. The minable coal seam is Two-2 with an average thickness of 3.54 m ，the average dip is 9.73. The proved reserves of this coal mine are 126.88 Mt and the minable reserves are 87.11 Mt, with a mine life of 55.8 a. The normal mine inflow is 894 m3/h and the maximum mine inflow is 1200 m3/h.

6、 The mine gas emission rate is 1.0 m3/t which can be recognized as low gas ，water inrush mine. Based on the geological condition of the mine, this design uses vertical shaft double-level development method, both district and strip preparation ,which divided into 3 strips and 5 distrits totally, The

7、first level is at -540 m, The second level is at -900 m .Track roadway, conveyor roadway and return airway are all rock roadways, arranged in the floor rock of Two-2 coal seam. The design apply strip preparation against the first band of One which divided into 10 stirps totally, and conducted coal c

8、onveyance, ventilation, gangue conveyance and electricity designing. The first stirps life is 16 months.The design conducted coal mining technology design against the 2106 working face. The coal seam average thickness of this working face is 3.54 m and the average dip is 8, the immediate roof is day

9、 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 f

10、ive working cycles per day, and the advance of working cycles is 4.0 m per day and 120 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 12 t skips to lift coal with a balance hammer and the au
