2、，属低瓦斯矿井；煤层无自然发火倾向，为易自燃煤层；煤尘有爆炸危险。矿井采用双立井单水平开拓，采煤方法为走向长壁采煤法。大巷采用带式输送机运煤，辅助运输采用1 t固定箱式矿车。设计首采区采用采区准备方式，工作面长度230 m，采用一次采全高采煤法，全部跨落法处理采空区。矿井采用“三八”制作业，两班半生产，半班检修。日进7个循环，循环进尺0.6 m，日产量4402.06 t。矿井采用两翼对角式通风。通风容易时期矿井总需风量3324 m3/min，矿井通风总阻力 693.3Pa，风阻0.226 Ns2/m8，等积孔2.50 m2，矿井通风容易。矿井通风困难时期矿井总风量3324 m3/min，矿井通

3、风总阻力1396.3 Pa，风阻0.459 Ns2/m8，等积孔1.76 m2，矿井通风中等困难。设计矿井的吨煤成本120.08 元/t。专题部分题目是回采巷道复合顶板破坏机理与支护技术。翻译部分是采矿活动诱发微震。英文原文题目为：Triggering of Seismicity Remote from Active Mining Excavations关键词：立井；上下山开采；采区；倾斜长壁采煤法；两翼对角式ABSTRACTThis design can be divided into three sections: general design, monographic study and

4、 translation of an academic paper.The general design is about a 1.5 Mt/a new underground mine design of dongrong coal mine. dongrong coal mine lies in jixian heilongjiang. the traffic is very convenient. Its about 7.0 km on the strike and 4.0 km on the dip,with the 28.0 km2 total horizontal area. Th

5、e minable coal seam of this mine is only one with an average thickness of 3.50 m and an average dip of 18.0. The proved reserves of this coal mine are 335.75 Mt and the minable reserves are 238.67 Mt, with a mine life of 106 a.The geological condition of the mine is relatively simple. The normal min

6、e inflow is 100 m3/h and the maximum mine inflow is 200 m3/h. It is anthracite coal spontaneous combustion tendency, and its a coal that has dust explosion.This mine adopts opening up by adits with one mining level. The adopted coal winning method is longwall mining to the dip or to the rise. Main r

7、oadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport.Designed first mining district makes use of the method of preparation in mining area, the length of working face is 230 m, which uses fully-mechanized coal mining technology, and fully caving method

8、to deal with goaf. The working system is “three-eight”,with two and half teams mining, and the other overhauling. Every mining team makes three working cycle, with seven working cycle everyday. Advance of working cycle is 0.6 m, and quantity of 4402.06 ton coal is makedeveryday.The mine makes use of

9、 diagonal ventilation method. At the easy time of mine ventilation, the total air quantity is 3324 m3 per minute, the total mine ventilation resistance is 693.3 Pa, the coefficient of resistance is 0.226 Ns2/m8, equivalent orifice is 2.50 m2. At the difficult time of mine ventilation, the total air

10、quantity is about 3324 m3 per minute, the total mine ventilation resistance is 1396.3 Pa, the coefficient of resistance is 0.459 Ns2/m8, equivalent orifice is 1.76 m2. The cost of the designed mine is 120.08 yuan per ton.The monographic study is deformation and failure mechanism and roof timbering t

11、echnique study on roadway of composite roof.The translated academic paper is about implications for stress measurement programs and numerical stability analysis of faults in mines. Its title is that triggering of Seismicity Remote from Active Mining ExcavationsKeywords：opening up by adits; up-dip an
