Th

4、is 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 mining area; 6.The method used in coal mining; 7. Transportation of the underground; 8.

5、The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Geting mine is located in Geting which comes within the jurisdiction of Jining in Shandong province. It is very convenient to get to the mine in terms of both highway and railw

6、ay. The length of the coalfield is 3.4 km,the width is about 2.8 km，and the total area is 10.45 km2.The third , the sixteenth and the seveneteenth are the main coal seams, and the design coal seem (the third) dip angle is 515 degree. The thickness of the mine is about 6.39 m in all. The geologic str

7、ucture of this coalfield is simple.The recoverable reserves of the coalfield are 126.20 million tons,and the minable reserves are 93.65 million tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 60.03 years. The normal flow of the mine is 99.

8、19 m3 per hour and the max flow of the mine is 248.3 m3 per hour. The relative mine gas gush is 2.98 m3/t and the absolute gush is 7.58 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

9、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 Geting mine. It produces for 330 days a year. This design includes ten chapters: Special part is the subject of working face through technical
