采用“吊盘法”测定了煤矿风巷、瓦斯巷、采区回风巷、运掘进巷的平均沉降速度、煤尘沉积强度等参数。用直方图、回归分析法等方法对测定和计算结果进行了具体的分析,根据分析结果提出了防尘建议。研究发现漳村煤矿的风巷、瓦斯巷煤尘沉积强度较低,运掘进巷煤尘沉积强度较高但离工作面越远越低,建议在现有防尘措施的基础上采用撒布岩粉、引进ZYB-S型自动产气式抑爆装置等方式抑制落尘变扬尘。
The “hanging plate method” was used to determine the parameters such as coal mine airway, gas lane, return air passage in mining area, average settlement speed of roadway for transportation, and deposition intensity of coal dust. Using histogram, regression analysis and other methods to the measurement and calculation results were analyzed in detail, according to the results of the proposed dust-proof recommendations. The study found that the wind and alley lanes of Zhangcun Coal Mine have lower strength of dust deposition and higher dust accumulation intensity of roadway and lower farther away from the working face. It is suggested to use spreading dust on the basis of existing dust control measures , The introduction of ZYB-S automatic gas explosion suppression devices and other ways to suppress falling dust and dust.
