The general part is a new design for Pansan mine. Pansan mine is located in northwest of Huainan ci
4、ty in Shandong province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 9.6km,the width is about 5.8km,and the total area is 54.3km2.The thirteenth is the main coal seams, and its dip angle is 510 degree. The thickness of the mine is abo
5、ut 3.75m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 330.96 million tons,and the minable reserves are 235.94 million tons. The designed productive capacity is 3.0 million tons percent year, and the service life of the mine is 60.5 years. T
6、he normal flow of the mine is 350m3 per hour and the max flow of the mine is 600 m3 per hour. The relative mine gas gush is 12.96 m3/t and the absolute gush is 58.71 m3/min, so it is a high gas mine. The mine is a two levels in two shafts to develop. Te central laneway uses Belt Conveyor to transit
7、coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is center juxtapose form.The “three-eight” working system is used in the Zhaizhen mine. It produces for 330 days a year. This design includes ten chapters: 1.An outline of the mine field

Underground transportation of the mine; 8.The lifting of the mine; 9. The ventilation and the safety ope
9、ration of the mine; 10.The basic economic and technical norms of the designed mine.The topic of special subject parts is the Analysis and appliation of pumping gas lane in floor which used in controlling gas. It makes a fully comprehensive statement of application pf pumping gas lane in controlling
10、gas.Translation part is aboat coal mine pillars by shortwall mining.The English title is “Backlling technology and strata behaviors in fully mechanized coal mining working face”.Keywords: Shaft; two levels; Panel; hybrid ventilation目 录一般部分1 矿区概述及井田地质特征11.1矿区概述11.1.1交通位置11.1.2地形、地貌11.1.3矿区气候条件11.1.4地
