It has ten chapters: the outline of the mine and the mine filed geology, boundary and reserves, the designed productive capacity and service life and working area, transportation of underground, mine lifting, mine ventilation and safety, and the economic and technologic index of the mine.The Jinggezhuang min
3、e filed lies in the Tangshan city of Hebei province. The boundary of the mine filed runs 4 km from Northeast to Southwest and 5.2km from West north to Eastsouth on average. The total area of the mine is about 20.8 km2.there are two available seams: 11#,12-2#, and the total thickness of the seams is 3.3m. It is stable belong to fluty inclined, with the average angle 7.1degree. The industry reserves of the mine filed are 191.9million tons and the useable reserves are 143.1 million tons. The averag
4、e flow of the mine is from 180m3/h. It is a low gassy mine. The coal dust doesnt have explosion hazard, and the seam has self-combustion tendency.The productive capacity of Jinggezhuang mine is 1.5million tons per year, and its service life is 68 years. There are unity level in the mine. The level has be located at the level of -500m .The coal minning method is fully mechanized mining to the longwill with sublevel caving in inclined coal seam.There is only one working face in the mine.
