1、附录 1 外文文献 Research on Waste Filling Technology and It s Matching Equipment in Coal Mining ZHANG Wen hai, ZHANG Ji xiong,ZHAO Ji Sheng,WEI Shu qun ,JU Feng 1、 The School of Information and Elect rical Engineering ,China University of Mining & Technology , Xuzhou ,Jiangsu 221116 , China ； 2、 Xingtai C

Ltd , Xingtai , Hebei 054000 , China ； 3、 School of Mining and Safety Engineering,China University of Mining & Technology,Xuzhou,Jiangsu 221116,China) Abstract : When the waste stowing technique is used in coal mining , the waste conveyor has some problems whic

3、h are (2)frequent movement of the conveyor (3)frequent dismounting of its frame (4)continuous shortening of the conveyor belt 4) the joint between the discharge end of the conveyor and the position where the wastes fill.Aiming at these problems,the existing DSP1010/ 650 conveyor which was of the hea

4、d-driving style was transformed into the tail-driving based on theoretical calculation , and an automatic tension device was installed for the telescopic belt conveyor . In addition , the waste filling technique was designed successf ully applied in Xingdong coal mine.The result shows that this matc

5、hing equipment not only can meet the requirement for waste filling technique but also is high in filling efficient,stable in performance,good reliability in its tension device,which has well solved the problem of slow filling resulted from the old matching equipment.Therefore,it is widely applied in

6、 waste treating of coal mines and t he coal mining under buildings. Key words : waste filling ； filling roadway ； tail-driving ； automatic tense equipment ； waste conveyor ； filling technology Coal production with lots of solid waste gangue emissions, the traditional approach is to the surface by un

7、derground coal accumulation, forming the unique characteristics of gangue surface buildings mountain.According to not complete count, the coal gangue piled up accumulated about 45 million t, large waste mountains and land occupied more than 1,600 about 1, 5 million ha, but also to 1 year accumulatio

8、n quantity, 5-2, 0 million t speed increase.Waste discharge for human survival environment and condition of the great threat and harm, mainly displays in: occupy land, Pollution of the environment, Human safety hazards.In addition, Chinas three (under buildings, railway, under water) a lot of coal r

9、esources backlog.According to statistics, Chinas production of coal mine TongPei only three under the pressure of coal, nine million t reached 137, among them.Under buildings, 68 million t, 94 total pressure coal 69 percent.Therefore, how to solve such coal resources recycling under buildings and wa

10、ste paper (mainly refers to the underground rock and coal from two rock cavern, from coal tunneling of downhole processing problem has already become the important technical problems of coal mining.Taking hebei Taurus energy shares of a limited liability company XingDong coal gangue as an example, studies the use of industrial buildings, filling the coal mining technology and square main auxiliary equipment, in order to solve the technical
