Mine Pit Hot Environment Forecast Technique Research And Numericl Simulation System Development

Along with the increasing deep of the coal mines and the improvement of mechanized extraction, the high-temperature and heat has become one of the most seriously problems in deep mines. The high-temperature environment in mine well is seriously threatening the safety in mine production and mine's physical and mental health. So, how to improve the climate state in mine well, to prevent heat hurting, and to ensure the safety in production of mine,and to accelerate the research of lowering the temperature theory in our country mine well has already become the urgent task in mine production.This research subject is based on the present problems situation of Chinese deep mines, summarized domestic and foreign in the wind warm prediction theory aspect research present situation and the level, has analyzed the question which still existed. In carries on the investigation and study to the national coal mine solution high temperature question's experience and the lesson in the foundation to absorb the existing research results, uses the method which the fundamental research and the computer simulation unify to conduct the research, forecast and design for the mine ventilation ability has provided the science basis.According to the mine pit loose wet exchange's principle, proposed the well lane wall surface moist humidity coefficient concept and the well lane terminal moisture content and the relative humidity computational method, uses the existing mathematical formula, Infers the tunnel temperature, the humidity and the amount of wind formula. The union computer visualization technology established a set of visualization degree to be high, the operating speed was quick, man-machine contact surface friendly, actual operation convenient computer software. Simulation predictive parsing mine ventilation and temperature decrease system transformation plan mine ventilation condition, determination ventilation system optimization plan; Achieves the mine ventilation and temperature decrease management the scientific style, realizes the mine ventilation and temperature decrease system's security to be reliable and mine pit main ventilator's security economy movement.
