摘要
以华阳集团开元公司9714综采工作面为研究对象,根据多组分输送和气固两相流理论,建立了等比容的全尺寸几何模型。模拟分析了不同气流分布条件下气体呼吸性粉尘耦合扩散规律,得到了在气体浓度完全稀释到安全范围的前提下最优排尘风量。此外,还测量了工作面内的风速、瓦斯浓度和呼吸性粉尘浓度,验证了模拟结果的准确性。
Taking 9714 fully mechanized mining face of Kaiyuan Company of Huayang Group as the research object, a full-scale geometric model with equal specific volume is established according to the theory of multicomponent transportation and gas-solid two-phase flow. The coupling diffusion law of gas respirable dust under different air distribution conditions is simulated and analyzed, and the optimal dust discharge air volume is obtained on the premise that the gas concentration is completely diluted to the safe range. In addition, the wind speed, gas concentration and respirable dust concentration in the working face are measured to verify the accuracy of the simulation results.
