| 摘 要： | 根据朱仙庄矿873综放工作面的实际情况,沿采空区倾向布置5个测点,对采空区气体成分及温度进行测定,确定出873工作面采空区自燃"三带"的范围.同时,根据通风网络理论建立了采空区滤流场的数学模型,以极限风速法为基础,利用VB与MATLAB进行混合编程编制了采空区自燃"三带"模拟软件,可直接绘制三带图并输出两条风速等值线所对应的坐标.由数值模拟得出的工作面极限推进速度与实际情况相符.最后,根据"三带"的范围确定了现场防灭火技术的实施工艺,有效地防治了采空区遗煤自燃,保证了工作面的安全回采.

| Abstract: | According to the actual situation of NO.873 fully-mechanized working face in Zhuxianzhuang coal mine,five testing points were located along its slope to measure gas component and temperature so as to determine the three-zone of spontaneous combustion in goaf.At the same time,according to the theory of ventilation network and limited wind speed method,a model for filtrating flow field in goaf was built and a simulation software for determining the three-zone in goaf was developed.The three-zone chart and the... |
