The design includes ten chapters: 1. Mine and mine geological features outlined; 2. Waida realm and reserves; 3. Mine system, design capacity and length of service; 4. Waida develop ; 5. to prepare the way - with the district roadway layout; 6. mining methods; 7. underground transport; 8. mine hoist; 9. mine ventilation and security technologies; 10. mine the basic technical and economic indicators.The Yuejin Ida is located in southeast of Yima City, Henan Province, the geographical coordinates: east longitude 111º,north latitude 34º. Ida northern is Longhai railway, LianHuo Highway and State Road 310, the mine with the convergence of dedicated railway and highway, and convenient transportation.Ida boundary: East from top to bottom within the coal seam Shen missing boundary, one five Disc area down the coal pillar push 200m for the community,west F8 fault.an area of about 18.3km2.Mine the maximum discharge is 63 m3/h, the normal discharge is 36 m3/h; coal to Clarain; all mine gas emission in the absolute maximum for the 6.8 m3/t, a low-gas mines; coal has a certain risk of spontaneous combustion , and the natural tendency of grade Ⅱ and coal dust explosion has a certain risk.Mine uses shaft double the level of development and uses Central parallel and the two wings of the roles of ventilation.Side of a mine ,mining method for a fully mechanized longwall mining all. Coal Transportation by the end of flame-retardant tape. Auxiliary transport uses battery Locomotive traction tramcar.The design applies mining area preparation against the first mining area of East One which divided into 5 mining area face totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 21101 face. The coal seam average thickness of this working face is 3 m and the average dip is 12°. The working face applies fully mechanized longwall mining all mining method, and uses double drum shearer cutting coal which cuts twice each working cycle.Mine is working days for 330 days, the net every day to enhance the time 16 hours. Mine system is “38“ structure.The thematic segment entitled Analysis of rockburst risk of roadway support. The article by the characteristics and hazards of the rockburst, as well as mode of action of zhe Bolt support Analysis the mechanism of Bolt support with rockburst risk of tunnel.The translation part of a thesis on the relationship between rockburst and civil engineering construction, the original English text entitled: How to model rockburst seismic loads for civil engineering purposes?Keywords:
