Heating device for increasing temperature of stope filling body and using method of heating device

Abstract

The invention discloses a heating device for increasing the temperature of a stope filling body and a using method of the heating device, and relates to the technical field of stope filling. The heating device for increasing the temperature of the stope filling body comprises a first flexible retaining wall, first grouting holes, first drainage holes, a metal wire mesh and anchor rods, and the first grouting holes are formed in the first flexible retaining wall. According to the heating device for increasing the temperature of the stope filling body and the using method thereof, the heating device is more suitable for the conditions that the stope environment temperature is too low and slurry is not prone to solidification, the internal temperature of the filling body can be increased, the solidification rate can be increased, the slump loss can be effectively controlled, and the bleeding property and porosity of the filling body are reduced through the water absorption of quick lime; meanwhile, the quick lime absorbs water and releases heat, and the solidification rate of the filling body is also improved.

Description

technical field [0001] The invention relates to the technical field of stope filling, in particular to a heating device for increasing the temperature of a stope filling body and a method for using the same. Background technique [0002] With the development of mining technology, in order to further reduce the mining cost and the needs of environmental protection, a series of new filling technologies have been developed to further improve the filling technology. However, whether it is cemented filling or paste filling, it will inevitably face the problem of delay in the solidification time of the slurry. After the filling slurry enters the goaf through a series of processes such as stirring, preparation and transportation, its solidification rate is not ideal due to factors such as external temperature and its own characteristics. [0003] In the prior art, especially in winter or under low temperature conditions, the solidification rate of the filling body is seriously aff...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a heating device for increasing the temperature of the stope filling body and its use method, which solves the problem of seriously affecting the filling body in the prior art, especially in winter or under low temperature conditions. This is also a problem that has plagued filling technicians for a long time. If the external temperature is not high enough, the filling body cannot solidify quickly, and the cement minerals will exist in the form of mud for a long time, which will directly affect the implementation of the filling mining method.
