摘要
以山西亚美大宁能源有限公司 9201 工作面为研究对象,基于"O"型圈理论使用Fluent软件对Y型通风工作面采空区后方气体分布特征进行数值模拟探究,并采用束管监测的方法对Y型通风工作面采空区进行"三带"现场测定,将测定结果与模拟结果进行比较验证,数值模拟结果与现场实测误差小于 5%,表明数值模拟与现场实测契合度较高,可为同一煤层相邻工作面采空区防灭火技术的实施提供数据参考.
Abstract
Taking the 9201 working face of Shanxi Yamei Daning Energy Co.,Ltd.as the research object,based on the"O"ring theory,Fluent software was used to numerically simulate and explore the gas distribution characteristics behind the goaf of the Y-shaped ventilation working face.The"three zones"field measurement of the goaf of the Y-shaped ventilation working face was carried out using the bundle tube monitoring method.The measurement results were compared and verified with the simulation results.The error between the numerical simulation results and the field measurement was less than 5%,indicating a high degree of fit between the numerical simulation and the field measurement,which can provide data reference for the implementation of fire prevention and extinguishing technology in the goaf of adjacent working faces in the same coal seam.
