The general part is a new design for Chaohua coal mine. Chaohua coal mine is located in Xinmi which comes within the jurisdiction of Zhengz

4、hou in Henan province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 3.6km,the width is about 2.6km，and the total area is 9.36km2.The second is the main coal seam, and its dip angle is 721 degree. The thickness of the mine is about 9.0m

5、 in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 121.08 million tons, and the minable reserves are 84.02million tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 53.8 years. The normal

6、 flow of the mine is 500m3 per hour and the max flow of the mine is 650 m3 per hour. The relative mine gas gush is 3.84m3/t and the absolute gush is 11.2 m3/min, so it is a low gas mine. The mine is vertical shaft development with two mining levels and the extension of vertical shaft. The central la

7、neway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is center juxtapose form.The “three-eight” working system is used in the Chaohua mine. It produces for 330 days a year. This design includes ten chapt

8、ers: 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 panels; 6. The method used in coal mining; 7. Underground transportation of the mine; 8.The lifting of the mine; 9.

9、 The ventilation and the safety operation of the mine; 10.The basic economic and technical norms of the designed mine.The topic of special subject parts is the Analysis of high yield and efficiency factors in caving face. The main working face is to study the impact of various factors, combined with

10、 case analysis. Translation part is mainly about on blasting in Coal Excavation.The English title is “APPLICATION OF BLASTING IN DRIVING TUNNEL”.Keywords: Shaft; Blind inclined shaft; two levels; Panel; Center juxtaposes ventilation; Coal caving mining目 录一般部分1 矿区概述及井田地质特征11.1矿区概述11.1.1地理位置与交通11.1.2地
