The general part is a new design for pingdingshanshikuang mine. pingdingshanshikuang mine is located in pingdingshan the distance

4、form the locate about 6km. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 8.42km,the width is about 3.32km，and the total area is 24.42km2.The fifth is the main coal seams, and its dip angle is 2.35.2 degree. The thickness of the mine is

5、about 10.9m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 473.37 million tons,and the minable reserves are 332.68 million tons. The designed productive capacity is 3.0 million tons percent year, and the service life of the mine is 78.89 year

6、s. The normal flow of the mine is 70m3 per hour and the max flow of the mine is 138 m3 per hour. The relative mine gas gush is 1.31 m3/t and the absolute gush is 10 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

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

8、 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 ope

9、ration of the mine; 10.The basic economic and technical norms of the designed mine.The thematic part of the subject is a coal mine coal and gas outburst prevention and control measures, mainly to study the characteristics of coal and gas outburst prevention measures, as well as coal and gas.
