摘要:Because of the high drivage ratio of ten thousand tons and a large amount of waste rocks, the upgrading capacity of the auxiliary shaft has reached its limits and harvesters supply is short especially in Kongzhuang Coal Mine. Authors put forward the underground waste-filling technical scheme suitable for this mine combing with the actual production and the existing tunneling technology, analyzed the main affect factors of the filling effects. The mine has chosen the suitable filling region and equipments and optimized construction technology. Through the investigation and analysis, this underground waste-filling technology system is simple, and requires less investment of equipments. Based on the analysis, it is incredible in both theory and technology that waste not rose to the ground and reduces the auxiliary shaft grading pressure in Kongzhuang Mine. It can also reduce the environmental pollution and ground subsidence, and achieve good economic and social benefits. So it is deserved to be promoted vigorously. © 2014 CAFET-INNOVA TECHNICAL SOCIETY. All rights reserved.
