一般部分为许疃煤矿2.4Mt/a新井设计。许疃煤矿位于安徽省宿州,区内交通十分便利。井田东西走向长7.9km,南北倾向宽3~4km,井田面积约26.5km2。井田内可采煤层共有2层,主采煤层为72煤。井田内72煤倾角在8~17°之间,平均厚度3m。矿井工业储量为349.66Mt,可采储量为265.91Mt,设计服务年限72.14a,第一水平服务年限79.14a。矿井正常涌水量为600m3/h,最大涌水量为650m3/h。矿井相对瓦斯涌出量为22m3/t,绝对瓦斯涌出量为12m3/min,属高瓦斯矿井。煤层无自然发火倾向,但煤尘有爆炸危险性。
井田开拓方式为立井单水平上下山开拓。大巷采用胶带输送机运煤,辅助运输采用防爆型蓄电池电机车牵引固定矿车运料。主井采用两对12t底卸式箕斗提煤,副井采用一对1.5t矿车双层四车加宽罐笼运送物料和升降人员。矿井通风方式为中央并列式通风。
矿井年工作日为330d,工作制度为“三八”制。两班半生产,半班检修。生产班每班完成3个采煤循环,检修班完成2个采煤循环。循环进尺为0.8m,日产量为6958t。

ABSTRACT
This design consists of three parts: the general part, special subject part and translated part.
The general design is about a 2.4 Mt/a new underground mine design of XuTuan Coal Mine. XuTuan Coal Mine lies in the west of SuZhou City, AnHui province. The transportation in the mining area is very convenient. It’s about 7.9 km on the strike and 3~4 km on the dip, with the 26.5 km2 total area. There are 2 minable coal seam. The main aquifer coal seam is 72 coal seam with an average thickness of 3 m, and the dip of 72coal seam is 8~17°. The proved reserves of this coal mine are 349.66 Mt and the minable reserves are 265.91 Mt, with a mine life of 79.14 a. The normal mine inflow is 600 m3/h and the maximum mine inflow is 650 m3/h. The mine relative gas emission quantity is 22 m3/t, and the absolute gas emission quantity is 12m3/min. Thus, it is a high gas mine. The coal seam has no spontaneous combustion tendency, but the coal dust has explosion hazard.
The mine is a single level in three shafts to develop. The central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway. The two main shaft to 12 t hoppers type skip carry coal, auxiliary shaft USES a pair of 1.5 t harvesters double four car transport materials and lift the cage widen personnel. The ventilation mode of this mine is center juxtapose form.
The “three-eight” working system is used in the mine. It produces for 330 days a year. Two and a half class production, half class maintenance. ShengChanBan each class complete three coal circulation, maintenance class complete two mining cycle. Circulation footage for 0.8 m, daily output for 6958 t.
This design includes ten chapters: 1. An outline of the mine field geology; 2. Boundary and the reserves of mine; 3. The service life and working system of mine; 4. Development engineering of coalfield; 5. The layout of panels; 6. The method used in coal mining; 7. Underground transportation of the mine; 8. The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10. The basic economic and technical norms of the designed mine.
The topic of special subject parts is Coal gas extraction technology research and application
Translation part is about The method of electromagnetic radiation forecast rock-burst. Its English title is “Hydraulic Sluiced Longwall Mining Without Supports”.
Keywords:Single level; Development engineering of coalfield; Center juxtapose ventilation; Gas extraction; Electromagnetic exploration
