3、应用，英文题目为： Application of Paste Backfill in Underground Coal Fires。关键词：立井；单水平；带区；中央并列式通风ABSTRACTThis design includes three parts: the general part, the special subject part and the translation part. The general part is a new design for Geting mine. Geting mine is located in Geting which comes within
4、the jurisdiction of Jining in Shandong province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 3.4 km, the width is about 2.8 km，and the total area is 10.45 km2. The third, the sixteenth and the seveneteenth are the main coal seams, and
5、 the design coal seem (the third) dip angle is 515 degree. The thickness of the mine is about 6.3 m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 126.20 million tons, and the minable reserves are 93.65 million tons. The designed productive c
6、apacity is 1.2 million tons percent year, and the service life of the mine is 60.03 years. The normal flow of the mine is 99.19 m3 per hour and the max flow of the mine is 248.3 m3 per hour. The relative mine gas gush is 2.98 m3/t and the absolute gush is 7.58 m3/min, so it is a low gas mine. The mi
7、ne is a single level in two shafts to develop. Te central laneway 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 Geting mine. It
8、 produces for 330 days a year. 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 panels; 6. The method used in coal mining;7. Unde
9、rground transportation of the mine; 8. The lifting of the mine; 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 water inrush in Coal Mining floor. It makes a fully comprehen
10、sive statement of its mechanism and the prevention means.Translation part is aboat paste backfill in underground coal fires. The English title is “Application of Paste Backfill in Underground Coal Fires”.Keywords: Shaft; Single level; Panel； Center juxtapose ventilation目 录一般部分1 矿区概述及井田地质特征1 1.1 矿区概述
