Abstract:

Aiming at the problems such as long ventilation distance of high-temperature and heat-hazardous mining area in deep mining of mines, long distance of underground cooling and cold transmission by ground industrial plaza refrigeration, and insufficient cooling and heat dissipation source of underground refrigeration, we put forward the technical program of travelling through strata cold transmission by ground level refrigeration and underground cooling.Through the structural construction and heat transfer analysis of the multi-layer composite heat preservation cold pipe, and experimental study on mechanical properties of filled insulation cement paste, and engineering implementation applications of“drilling first,finding after”construction process for traversing through strata, the technical program of travelling through strata cold transmission by ground level refrigeration and underground cooling was validated as Feasible.The cooling system is safe, stable and reliable, The cooling system is safe, stable and reliable, and the effect of underground centralized cooling system is remarkable, which can effectively meet the cooling demand of the working face, and effectively solves the problem of Heat dissipation challenges of cooling and refrigeration in the well, shortens the cooling distance, ensures the cooling efficiency.It also avoids the problem of coal safety and explosion-proof of the refrigeration unit in the well, and the refrigeration system is easy to maintain which has gained good economic and social benefits.
