1、第156页 摘 要一般部分为淮北矿业集团袁一煤矿1.2Mt/a新井设计。袁店一矿西部边界为袁店断层为界，东至32煤层-950 m的水平投影线和39467500经线，南从杨柳五沟断层及10煤层露头线，北到32煤层-950 m的水平投影线和区块登记边界。东西长约6.913.6 km，南北宽1.23.4 km，井田面积约35.98 km2。主采煤层为10煤，煤层倾角为515，平均约10，属于缓倾斜煤层，煤层平均厚度为3.9 m。井田工业储量为129.57 Mt，矿井可采储量90.47 Mt。矿井服务年限为53.9 a，第一水平服务年限25.2 a。矿井正常涌水量为392 m3/h，最大涌水量为584

2、 m3/h。矿井最大相对瓦斯涌出量10.08 m3/t，属于高瓦斯矿井。井田开拓方式为立井两水平暗斜井延开拓，井田采用采、带区式布置方式，共划分为二个采区，十个带区，轨道大巷、胶带机大巷和回风大巷皆为岩石大巷，布置在10煤层底板岩层中。针对西六带区采用了带区准备方式，共划分5个回采工作面，并进行了通风、运煤、运料、排水、排矸、供电系统设计。针对10601工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.9 m，平均倾角11.3。矿井年工作日为330 d，工作制度为“四六”制，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。截深0.8 m，每天六个循环，循环进尺4.8

3、 m，月推进度144 m。大巷采用胶带输送机运煤，辅助运输采用电机车牵引固定矿车运料。矿井通风方式前期为中央分列式，中期为中央并列式，后期为中央分列式通风。主井采用两套带平衡锤的12 t箕斗提煤，副井采用一对1.5 t矿车双层四车窄罐笼和一个带平衡锤的1.5 t矿车双层四车宽罐笼运料和升降人员。专题部分题目是泥化巷道底板控制技术。翻译部分主要内容是复合载荷下沙层地基运转塑性模型，其英文题目为：A plasticity model for the behaviour of footings on sand under combined loading。关键词：袁一煤矿；暗斜井；大断面巷道；大采高

4、一次采全厚采煤法；中央并列式ABSTRACTThe general part is a new design for YuanDian mine. Yuan Dian mine in west is bounded Yuan Dian fault; East to 32 coal-950m level projection lines and 39467500 at warp; South from a willow 5 ditch fault and 10 coal seam outcrop lines; North to 32 coal-1000 m level projection li

5、nes and block registration boundary. The length of the minefield is about 6.9 13.6km, north and south wide 1.2 3.4 km, field with an area of about 35.98km2. The 10# is the main coal seam. The dip angle of the coal is 515 degree and the average one is 10 degree. The average thickness of the coal is 3

6、.9m in 10#.The proved recoverable reserves of the minefield are 129.57 million tons, and the minable reserves are 90.47 million tons. The designed productive capacity is 1.2 million tons per year, and the service life of the mine is 53.9 years. The normal flow of the mine is 392m3 per hour and the m

7、ax flow of the mine is 584m3 per hour. The relative mine gas gush is 10.08m3/t, It is a high gas mine. The mine is a double level dark tilt extending depth and concentration rock roadway to develop and full strip preparation, which divided into three working areas and eight bandts, and track roadway

8、, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 10# coal seam.The design applies strip preparation against the first band of West Two which divided into 5 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity desi

9、gning. The design conducted coal mining technology design against the 10601 face. The coal seam average thickness of this working face is 3.9m and the average dip is 11.3. The “four-six” working system is used in the mine. It produces for 330 days a year. The working face applies fully mechanized lo

10、ngwall full-height coal caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. The depth-web is 0.8m with six working cycles per day, and the advance of a working cycle is 4.8m and the advance is 144m per month.The central laneway uses Belt Conveyor to transit

11、coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is earlier stage which using boundary juxtapose form and later stage which using center juxtapose form. The main shaft uses double 12t skips to lift coal with a balance hammer and the au

12、xiliary shaft uses a twins narrow1.5t four-car double-deck cage and a wide 1.5t four-car double-deck cage to lift material and personnel transportation.The topic of special subject parts is the restoration technology of large section and loose-fractured Instability roadway which in high seepage pres

13、sure.Translation part is about the useage of coal mine of US, and discusses to set up a mechanical anchor system to improve the performance of bolt. Its English title is “A plasticity model for the behaviour of footings on sand under combined loading”.Keywords：Yuandian coal mine; Blind inclined shaf
