Huayuan mine is located in Jinxiang which comes within the jurisdiction of Ji’ning 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 3.9km,the width is about 3km, and the total area is 13.97km2.The fifteenth are the main coal seams, and its dip angle is 2~12 degree. The thickness of the mine is about 7.5m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 147.75 million tons,and the minable reserves are 124.97 million tons. The designed productive capacity is 1.5 million tons percent year, and the service life of the mine is 59.50 years. The normal flow of the mine is 86m3 per hour and the max flow of the mine is 99 m3 per hour. The relative mine gas gush is 1.732 m3/t and the absolute gush is 6.866 m3/min, so it is a low gas mine. The mine is a single level in two shafts to develop. Te central laneway uses Belt Conveyor to transit 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 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 Numeric Analysis of Hydraulic Fracturing Technique in Preventing Outburst and the Control Technique Translation part is aboat coal mine pillars by shortwall mining.The English title is “Exploitation of developed coal mine pillars by shortwall mining—a case example”.Keywords: Shaft; Single level; Panel; Center juxtapose ventilation目 录一般部分1
