Tashan mine. Tashan mine is located in Nanjiao which comes within the jurisdiction of Datong in Shanxi province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 3.51km,the width is about 3.45km,and the total area is 9.54km2.The second and the fifth are the main coal seams, and its dip angle is 2 degree,except the eastern outcrops in steep. The thickness of the mine is about 18.05m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 245.72 million tons,and the minable reserves are 159.82 million tons. The designed productive capacity is 2.40 million tons percent year, and the service life of the mine is 51.2 years. The inflow is little.The normal inflow of the mine is 610m3 per day and the max inflow of the mine is 1620 m3 per day. The relative mine gas gush is 2.56 m3/t and the absolute gush is 0.52 m3/min, so it is a low gas mine. The development of the mine is single level with vertical shaft. The number of the working faces is only one. Mining method is integrated mechanized slicing top coal caving.The central laneway uses Belt Conveyor to transit coal.And trackless tire vehicle is using for auxiliary transport.The ventilation mode of this mine is center juxtapose form.The “thirty-eight” working system is used in the Tashan mine. It produces for 330 days a year. 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 “Technology and Practice of Improve the recovery rate of coal resources” .Translation part is “The developing trend of fully mechanized mining and caving technology and the rational supports”.Keywords: Shaft; Single level; Panel; Center juxtapose ventilation; coal caving第 页目 录一般部分1 矿区概述及井田地质特征
