説明
Numerous studies have been made to control the climate conditions in underground mines, but most of them are concentrated on a single roadway with through airflow, and those on the simulation of heat problems in developing roadway with local ventilation are very few. Therefore it is necessary to establish a proper method to simulate the thermal environmental conditions within the working face with auxiliary ventilation for controlling the thermal climate there effectively.<BR>As a basic study on control of the thermal environment in working face with auxiliary ventilation, the CFD method is employed to simulate the transfer of heat and moisture between rock surface and the airflow at a heading face with forcing auxiliary ventilation. Based on the simulation results, the distribution of local heat-transfer coefficient and its relationship with airflow rate, variation of heat transfer flux from the strata to the ventilation air with time and wetness fraction, the distribution of rock temperature and its variation with time elapse are discussed in the paper.<BR>The study provides an important basis for establishing a proper method to predict the thermal environment conditions on locally ventilated working places.
