3、of Yunhe Mine of coal departmentIt has ten chapters:an outline of the mine and mine field eology, boundary and resgrves, productive capacity and service life and working area, mine field development, preparation road, coal mining method, transportation of underground, mine lifting, mine ventilation

4、and safety, the economic and technologic index of the mineThis Minefield lies in the special area of Jining cityThe total area of the mine is 14 km2The boundary of the mine field runs 3.5 km on north south and 4 km on westeast on averageThere only is one exploring layer:No.3#, and the average thickn

5、ess of the seam is 8.64 mIt is stable and flat seam. Its dip angle is from 10 to 20 degree, and is 15 degree on averageit is a low gassy mineThe coal dust has explosion in hazard. the seam has self-combustion tendencyThe productive capacity of Yunhe Mine is 1.8 million tons per year, and its service

6、 life is 76.1 years, two working face is used sametime in the mineThe mine only has two levelsIt gets third vertical shafts: the main shaft, the subsidiary and return airflowThe first designed development level should be located at the level of -490mThe coal mining method is fully mechanized minmg t

7、o the trend with sublevel caving in roofcoalThere is only one working face , It is used comprehensive mechanized coal face and each productive capacity is 1.8 million tons per yearThe length of the longwall face is 180mThe coal is transported by The coal is transported by the single-track drop-botto

8、m car of 3 tons and the rubber tyre car is used in the ancillary transportThe method of mine ventilation is centralized paratactie ventilationThe special subject of the paper is about bolt support Technology in 3 soft coal lane The translation part is about the Technology for Tomorrow and Equipment

12、露头，北起F11断层，南至BF7断层和T59与A2416孔连线垂切与唐口井田分界。井田东西长约4km，南北宽约3.5km，面积约14km2。1.1.2 交通运河井田位于山东省济宁市西北郊的南张乡境内，属唐口勘探区。距济宁市约10km。本区水、陆交通方便。兖新铁路从济宁经过，西经菏泽与京九铁路相接，至新乡与京广铁路相接，东至兖州与津浦铁路接轨，再往东经临沂可至石臼所。井田东部有105国道（北京珠海），南部有327国道和济宁梁山公路。纵贯南北的京杭大运河从井田西侧流过，大型运输船队直达长江，钱塘江各口岸，运河支流跃进沟从井田中央流过，河宽水深，稍加修建将是一个天然的货运码头，船队可直接在井田内装货，经运河直接流向江浙、上海。井田距济宁机场30km，该机场已开通济宁至广州、上海、北京等航线。水路、陆路、铁路、航空、交通运输四通八达。矿井交通位置如图111.1.3 地形与河流区内地形平坦，地面标高+35+38m，地势东北部略高，东南部略低，地形坡度万分之二左右。井田中部有南跃进沟，其与西北流向的天宝寺沟在井田西部边界汇合并连接京杭运河1.1.4气象
