摘    要：硐室型采场中的平均风速一般都很小,可把该流场性质假定为势流.在这一假设前提下,通过应用流体有限元法和微机对不同边界条件的硐室型采场流场进行分析,再把分析结果与工业通风中建立的房屋通风数模结合起来,对硐室型采场中的炮烟浓度、通风时间、通风体积、需风量等参数以及不同的采场几何形状进行计算机模拟.研究结果对硐室型采场通风效果的改善及环境污染监测等具有重要的意义.

Abstract: Because of the fact that the average air velocity in large mine openings is very small in mostcases, the flow property in these openings can be assumed as potential flow. According to the assumption, the flow field in the openings with different boundary conditions has been analyzed by finiteelement method (FEM) and micro-computer. Combining the analyzed results with the ventilatingmathematical model used for rooms in industrial ventilating field, the relationship among the blastfume concentration, air flow rate, ventilating time, opening volume and geometric conditions, etc. has also been simulated by micro-computer. These research results are very significant for improving the ventilation effect and the environmental monitoring in large mine openings.
