The general part is a new design of 1.

4、2 million tons per year of NO.4 of Pingdingshan mine. 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 mining area; 6.The method used

5、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 NO.4 mine located in the middle of Pingdingshan mine area. And its 6km away from the southeast of the town. It has

6、a length of 5.2 km in the east and west direction while a width of 3.6 km in the south and north direction on average. The total area is Approximately 19.7 km2. The main coal seam in the mine is only one, which is the amyl 10# coal seam. The average thickness is 4.0 m, while the angle is about 9 deg

7、ree. The normal mine inflow is 427 m3/h and the maximum mine inflow is 673 m3/h. The absolute gas emission is 4 m3 per ton. Thus it is Low gaseous mine. It has no tendency of spontaneous combustion, which belongs to not easy to spontaneous combustion coal. But the coal dust of the mine has explosion

8、 hazard. The geological coal reserves is 114.84Mt; and the industrial reserves is 112.5Mt, the design resource reserves is 109.17 Mt; while the design recoverable reserves is 85.60Mt; The service life is 51 years.According to the geological conditions, the development of the mine chose a single leve

9、l with shaft. The number of the working faces is only one, which using the band-style layout. The ventilation type is centralized parallel. The working days in a year are 330. Every day it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”. The coal mining process is

10、 a full-height, and the belt conveyers undertake the job of coal transport in the mine.The title of the special subject part is” the analysis of the deep and soft rock roadway support in the NO.4 mine”, which described the deformation of the soft-deep rock roadway and the latest methods of support a

11、t home and abroad .according to a comparative analysis, we chose the support which is more suitable to the NO.4 mine, and it has the guiding significance for the mine production in practices.The translation parts title is” Environmental issues from coal mining and their solutions”, which analyzed th
