Baodian coal mine is located in Zouchen, Shangdong province. It’s about 7.2 km on the strike and 5.06 km on the dip, with the 35.1 km2 total horizontal area. The minable coal seam is 3(3up、3down) with an average thickness of 8.81 m and an average dip of 8.9°. The proved reserves of this coal mine are 399.267Mt and the minable reserves are 276.470 Mt, with a mine life of 70.89a and the first level life 50.57a. The normal mine inflow is 100m3/h and the maximum mine inflow is 300 m3/h. The mine gas emission rate is 1.5 m3/t which can be recognized as gas mine. Based on the geological condition of the mine, this design uses a duel-vertical shaft two-level development method with combination of bands and districts style. The first level of elevation is located on -375 m, the second level of elevation is located on -500m, divided into four districts and five bands, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 3 coal seam. The pre method use central parallel ventilation and the post-mine ventilation is central-past ventilation (boundary type). The design applies strip preparation against the first band of North One which divided into 26 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 3102 face. The coal seam average thickness of this working face is 8.5 m and the average dip is 6.2°. The working face applies top coal caving, and uses double drum shearer cutting coal which cuts twice each working cycle. "Four-Six" working system has been used in this design and the depth-web is 0.8 m, a working cycle is 1.6 m with three working cycles per day, and the advance of and the advance is 132 m per month. Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses double 12 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.5 t four-car double-deck cage and a wide 1.5t four-car double-deck cage to lift material and personnel transportation. The thematic segment entitled "Treatment Technologies for deep high-temperature mine heat damage, elaborating the research status quo at home and abroad to mine heat damage theory, technology, and based on lack of existing theory, a preliminary experiment to explore about new active cooling with insulation materials injection to underground roadway was conducted. The title of the translated academic paper is “Modeling and Simulation of the Underground Mining Transportation System ", mainly introducing a system simulation to optimize the model in a large underground coal mine transport systems.
