袁店一矿180万吨新井设计.docx

1、摘 要一般部分为淮北矿业集团袁店一矿180万吨新井设计。袁店一矿西部边界为袁店断层为界，东至32煤层-1000m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-1000m的水平投影线和区块登记边界。东西长约6.913.6km，南北宽1.23.4km，井田面积约37.22km2。主采煤层为8煤和10煤，其中8煤位于10煤上部，两煤层间距平均约80m，煤层倾角为515，平均约10，属于缓倾斜煤层，煤层平均总厚为8煤3.5m、10煤3.6m。井田工业储量为214.47Mt，矿井可采储量148.23Mt。矿井服务年限为58.8a，第一水平服务年限28a。矿井正常涌水

2、量为392m3/h，最大涌水量为584m3/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深集中岩石大巷开拓，井田采用采、带区式布置方式，共划分为三个采区，八个带区，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。针对西二采区采用了采区准备方式，共划分3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8201工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.5m，平均倾角15。矿井年工作日为330d，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

3、深1.0m，每天六个循环，循环进尺6.0m，月推进度165 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，后期为中央并列式通风。主井采用两套带平衡锤的16t箕斗提煤，副井采用一对1.0t矿车双层四车窄罐笼和一个带平衡锤的1.0 t矿车双层四车宽罐笼运料和升降人员。专题部分题目是高渗透压松散破碎大断面失稳巷道修复技术。翻译部分主要内容是美国煤矿锚杆安装质量改善研究，其英文题目为：Improving Rockbolt Installations in US Coal Mines。关键词：袁店一矿；双立井；采区布置；中央并列式；大断面巷道；修复技术；锚

4、杆性能ABSTRACTThe general part is a new design for YuanDian mine. Yuan Dian mine in west is bounded Yuan Dian fault; East to 32 coal-1000m 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 lines and bl

5、ock registration boundary. The length of the minefield is about 6.9 13.6km, north and south wide 1.2 3.4km, field with an area of about 37.22km2. The 8# and 10# is the main coal seam. And the 8# is above the 10# with a vertical distanceof about 80m. The dip angle of the coal is 515 degree and the av

6、erage one is 10 degree. The average thickness of the coal is 3.5m in 8# and 3.6m in 10#.The proved recoverable reserves of the minefield are 214.47 million tons, and the minable reserves are 148.23 million tons. The designed productive capacity is 1.8 million tons per year, and the service life of t

7、he mine is 58.8 years. The normal flow of the mine is 392m3 per hour and the max 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 preparati

8、on, which divided into three working areas and eight bandts, and track roadway, 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 3 stirps totally, and

9、conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 8201 face. The coal seam average thickness of this working face is 3.5m and the average dip is 15. The “four-six” working system is used in the mine. It

10、 produces for 330 days a year. The working face applies fully mechanized longwall full-height coal caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. The depth-web is 1.0m with six working cycles per day, and the advance of a working cycle is 6.0m and the a

11、dvance is 165m per month.The central laneway uses Belt Conveyor to transit 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 mai

12、n shaft uses double 16t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.0t four-car double-deck cage and a wide 1.0t four-car double-deck cage to lift material and personnel transportation.The topic of special subject parts is the restoration technology of large

13、 section and loose-fractured Instability roadway which in high seepage pressure.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 “Improving Rockbolt Installations in US Coal Mines”.Key
