The general part is a new design of Qidong 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 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 Qidong mine locates at the crosspart of Qixian, Xisipo and Guzhen of Suzhou in Anhui province, 20 km away from the center of the town. And the transportation is very convenience. The shape of minefield is like a rectangle which has a length of 9 km in the east and west and a width of 3 km in the south and north on average. The total plane area of the mine is about 24 km2. There are two coal seams in the mine —NO.61 and NO. 71. Mining the NO.61 coal seam firstly.The angle is about 9.05~13.8 degree with an average of 12 and the thickness of both coal seams is about 7.0 m. The minefield geological condition is simple. The proved reserves of the minefield are 330.2297 million tons. The recoverable reserves are 220.6853 million tons. The designed productive capacity is 3.0 million tons per year. The service life is 61.3 years. The normal water flow of the mine is 437 m3 per hour and the max water flow is 586 m3 per hour. The Relative gas discharge quantity is 10 m3 per ton, whichmeans it is a high gaseous mine. The coal seam is hardly spontaneous combustion and the level of spontaneous combustion is Ⅲ. Apart from coal without gas, the coal seam is of high explosion hazard. The development of the mine is double levels with vertical shaft at the first level and inclind shaft at the second level. The number of the working faces is only one. The mining method is Comprehensive mechanization with putting off the top coal technology. Several belt conveyers undertake the job of coal transport in the mine and the auxiliary transportation system is centralized juxtapose. The ventilation method is diagonal ventilation system. The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “four-six”. The title of the special subject part is “Underground Coal Gasification in mining technology basic research”. By some examples of coal mine project, analyzed and calculated by modeling, Study the mobility characteristics of the roof strata in underground coal gasification process, the variation of the semi-coke pore structure in the process of underground coal gasification and underground coal gasification process in the overburden rock stress field value, conclusions drawn on these three aspects wind stress, the evolution of deformation is obtained when the dual roadway deformation, Deputy Lane by the basic law of mining and the left pillar set a reasonable size, with similar conditions Roadway reference. The translated academic paper is about classification technique for danger classes of coal and gas outburst in deep coal mines. Its title is “Simulation of CO2-geosequestration enhanced coal bed methane recovery with a deformation-flow coupled model”.
