3、 新井设计； 井田开拓； 采煤方法；一次采全高ABSTRACTThis design consists of three parts: the general part, the special part and translated part.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 engi

4、neering of coalfield; 5.The layout of panels; 6. The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.The general part is a new design of xiandewang mine. xi

5、andewang mine lines in Northwest of xingtai in HeBei province. The traffic of road and railway is very convenience to the mine. The geological structure of this area is simple. The Length of the minefield is 5 km ,the width is about 4km，the area is 202.The 2 and 9 is the main coal seam, and its dip

6、angle is 14 degree. The thickness of the mine is about 7.0m in all. The proved reserves of the minefield are 148million tons. The recoverable reserves are 105 million tons. The designed productive capacity is 15 million tons percent year, and the service life of the mine is 53.8 years. The normal fl

7、ow of the mine is 140m3 percent hour and the max flow of the mine is 200m3 percent hour, and the gas of the mine is low gaseous mine.The field has been divided one mining levels. The first level should be located at the lever of -50m, which use raise and dip mining method of vertical shaft developme

8、nt . The main shaft skip install skip and the auxiliary shaft install cage. Roadway use belt conveyor to transport coal, the use of auxiliary transport Renovation of 1.5t Van tub transport. The two wings opposite angles ventilation system is used in the mine. The working system “three-eight” is used

9、 in the x mine. It produced 330d/a.Special section entitled: Analyse of mechanism about anchor and slip casting in roadway surrounded by cracked stone.Translated part of the title is: Effects of frequency and grouted length on the behavior of guided ultrasonic waves in rock boltsKeywords : New Well
