3、Movement characteristics of Karst water in a deep mining area ABSTRACTThis design includes of three parts: the general part, special subject part and translated part.The general part is a new design of Qijiapo mine. Qijiapo coal lies in the Northwest Qianyangxian, an adjoining town of Longxian in th
4、e city of Baoji, ShangXi province. The traffic of road and railway is very convenience to the coal. The run of the minefield is 3.2km,the width 3.7km，the well farmland total area is 11.87km2. There are two seams of coal，The Lower is the main coal seam, and its dip angle is 8degree. The thickness of
5、the mine is about 8.0m in all. Geologic structure of coalfield is simple.The proved reserves of the minefield are 89.48 million tons,and the recoverable reserves are 56.34 million tons. The designed productive capacity is 0.9 million tons percent year, and the service life of the mine is 45.8 years.
6、 The normal flow of the mine is 5.8m3 percent hour and the max flow of the mine is 7.5 m3 percent hour. The mineral well gas gushes is lower, It is a low gas mineral well. The mine is a single level in an vertical well to expand. Te central laneway use Hoppers type harvesters of 3.0t to transit coal
7、, Fixed harvesters and peaceful type harvesters of 1.0t are used for accessorial transportation in te roadway.The working system “three-eight” is used in the Mugua mine. It produced 330 d/a.This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine
8、; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of belt; 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 techni
