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. It’s about 7.0 km on the strike and 4.0 km on the dip,with the 28.0 km2 total horizontal area. The 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 mine inflow is 100 m3/h and the maximum mine inflow is 200 m3/h. It is anthracite coal spontaneous combustion tendency, and it’s 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 roadway 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 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 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 N·s2/m8, equivalent orifice is 2.50 m2. At the difficult time of mine ventilation, the total air quantity is about 3324 m3 per minute, the total mine ventilation resistance is 1396.3 Pa, the coefficient of resistance is 0.459 N·s2/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 technique 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 Excavations Keywords：opening up by adits; up-dip and down-dip minging; strip district ; longwall mining to the dip or to the rise; diagonal ventilation 1
