1、摘 要一般部分针对田庄煤矿进行了井型为1.5Mt/a的新井设计。田庄煤矿位于山东省兖州市境内，井田南北长约6.5km，东西宽3.37.0km，面积约25.87km2。主采煤层为16上#煤层，平均倾角6，平均厚度4.8m。井田工业储量为161.59Mt，可采储量105.46Mt，矿井服务年限为50.2a。矿井正常涌水量为120m3/h，最大涌水量为340m3/h；矿井相对瓦斯涌出量为54.08m3/t，属低瓦斯矿井。根据井田地质条件，设计采用双立井单水平开拓方式，井田采用全带区式布置方式，共划分为两个带区，两个盘区，轨道大巷、胶带机大巷和回风大巷皆为煤层大巷，布置在16上煤层中。针对东一带区采用
2、了带区准备方式，共划分5个分带工作面，并进行了运煤、通风、运料、排矸、供电系统设计。针对16101工作面进行了采煤工艺设计。该工作面煤层平均厚度为4.8m，平均倾角6，直接顶为泥岩，老顶为细砂岩。工作面采用长壁综采一次采全高采煤法。采用双滚筒采煤机割煤，往返一次割两刀。采用“三八制”工作制度，截深0.8m，每天四个循环，循环进尺3.2m，月推进度96m。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16t箕斗提煤，副井采用一对1.5t矿车双层四车窄罐笼和一个带平衡锤的1.5t矿车双层四车宽罐笼运料和升降人员。专题部分题目为绿色开采技术理论及可行性分析
3、，就目前的采矿现状所产生的问题针对的提出的绿色开采技术的理论和可行性研究分析。翻译部分题目为Review of roadway control in soft surrounding rock under dynamic pressure，论文分析了动压软岩巷道的基本特点，提出了围岩控制的三个基本途径：提高围岩强度、降低岩体应力、选择合理的支护技术。关键词：田庄煤矿；双立井；带区布置；综采大采高 ABSTRACTThe general design is about a 1.50 Mt/a new underground mine design of Tianzhuang coal mine.
4、 Tianzhuang coal mine is located in Yanzhou, Shandong province. Its about 6.5 km on the strike and 3.2 km on the dip, with the 25.87 km2 total horizontal area. The minable coal seam is 16# with an average thickness of 4.8 m and an average dip of 6. The proved reserves of this coal mine are 161.59 Mt
5、 and the minable reserves are 105.46 Mt, with a mine life of 50.2 a. The normal mine inflow is 120 m3/h and the maximum mine inflow is340 m3/h. The mine gas emission rate is 54.08 m3/t which can be recognized as high gas mine. Based on the geological condition of the mine, this design uses a duel-ve
6、rtical shaft single-level development method, and full strip preparation ,which divided into eight bands and two districts, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 16# coal seam. Taking into account of the high gas emission, min
7、e ventilation method use two diagonal wings ventilation, and excaves bottom gas drainage roadway before mining to relief gas pressure in advance.The design applies strip preparation against the first band of East One which divided into 5 stirps totally, and conducted coal conveyance, ventilation, ga
8、ngue conveyance and electricity designing.The design conducted coal mining technology design against the 160101 face. The coal seam average thickness of this working face is 4.8 m and the average dip is 6, the immediate roof is mud stone and the main roof is sand stone. The working face applies full
9、y mechanized longwall full-height coal caving method, and uses double drum shearer cutting coal which cuts 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 a working cycle is 3.2 m and the
10、 advance is 96 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 narrow1.5 t four-car double-deck cage and a w
11、ide 1.5t four-car double-deck cage to lift material and personnel transportation.The monographic study entitled Review of roadway control in soft surrounding rock under dynamic pressure , the study took 1111(1) bottom gas drainage Roadway of Tianzhang Mine as an example, conducted a detailed pressur
12、e observation data collection and processing, gave the deformation and convergence law of soft rock roadway, which had significant guidance for practical mine production.
