摘要:
矿山溜井卸矿过程中产生的大量冲击性粉尘已成为矿井可呼吸性粉尘的主要来源，为了有效解决溜矿井卸矿时产生的大量冲击性粉尘，基于泡沫抑尘的机理，研究了发泡倍数和半衰期两个指标进行优选实验，通过正交法和单因素法优选出最佳的泡沫抑尘配方为十二烷基硫酸钠、月桂酸钠和聚丙乙酰胺，各成分的质量浓度分别为0.6%、0.8%与0.4%。结果表明，通过模拟溜井卸矿测得不同泡沫高度的抑尘效率在85%~95%之间，呼吸性粉尘的抑尘效率为87%左右，其时效性可达2h以上。
Abstract:
Plenty of impact dust produced in the ore discharge process of mine ore pass has become the main source of respirable dust in mine. To effectively solve this problem, based on the mechanism of foam dust suppression, two indexes including foaming multiple and half-life were selected to carry on the optimization experiment. Through the orthogonal method and single factor method, the optimal formula of foam dust suppression was obtained. The ingredient included sodium dodecyl sulfate, sodium laurate and poly propylene acetamide, and the mass concentration of each component was 0.6%, 0.8% and 0.4% respectively. The results showed that, by simulating the ore discharge process in mine ore pass, the dust suppression efficiency of different foam height was measured as between 85% ~ 95%, and the dust suppression efficiency of respirable dust was about 87%, with the timeliness as more than 2h.
