Background

The shaft assumes the tasks of gangue removal, transport of personnel, equipment, materials, and ventilation in mine construction.

In one prior art technique, mine slag is removed from a mine during construction through a vertical shaft. However, when being in high altitude area or the lower region of temperature is under construction, the easy problem that the slabstone glues on the chute surface that is used for transporting the slabstone that appears directly influences sediment efficiency to, after the slabstone that adheres to on the chute can not receive effective processing for a long time, then the condition that the chute freezes can appear, then further influences sediment efficiency and normal production, also has great potential safety hazard simultaneously.

In order to solve the problems, in the prior art, a coal stove or charcoal is arranged at the bottom of a chute and the chute is heated, so that the surface of the chute keeps a certain temperature, and the slag is prevented from freezing in a cold construction environment. However, in this way, on one hand, because the furnace is in cold condition, it is difficult to heat sufficiently by simple coal stove or charcoal, and the heat loss is obvious, so that the chute is difficult to maintain a certain temperature to avoid the slag from freezing; on the other hand, the site operation has open fire itself, so that the potential safety hazard to mine construction is large, and the environment protection is not facilitated. In addition, because the coal or the charcoal required by combustion needs to be added repeatedly, a certain high-altitude operation risk exists for constructors, and the labor intensity is obviously improved because the fuel consumption is obvious.

Therefore, the prior art should be improved to solve the problems that the chute slag stone freezing in the prior art is difficult to be effectively treated, the treatment risk coefficient is high, and the labor intensity is high.
