The general part is a new design for Tianchen mine. Tianchen mine is located

4、 in Xintai which comes within the jurisdiction of Tengzhou 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 3.7km,the width is about 7.32km，and the total area is 27.15km2.The fourth and the sixth are the main coal sea

5、ms, and its dip angle is 1.320.56 degree. The thickness of the mine is about 5.0m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 180.4million tons,and the minable reserves are 127.76 million tons. The designed productive capacity is 1.5 milli

6、on tons percent year, and the service life of the mine is 60.8 years. The normal flow of the mine is 373m3 per hour and the max flow of the mine is 400 m3 per hour. The relative mine gas gush is 1.33 m3/t and the absolute gush is 2.0m3/min, so it is a low gas mine. The mine is a single level in two

7、shafts to develop. Te central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilated way of opposite angle of two wing was used.The “three-eight” working system is used in the Tianchen mine. It produces for 330 days a year

8、. 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 min

9、e; 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 the Analysis of Gob-side Entry Retaining Technology in Mechanized Mining Face. It makes a fully comprehensive st

10、atement of gob-side entry retaining technology in mechanized mining face.Translation part is aboat Passive Gamma Ray Instruments was used in Coal Mines.The English title is “Remnant Roof Coal Thickness Measurement with Passive Gamma Ray Instruments in Coal Mines”.Keywords: Shaft; Single level; Panel
