| 摘 要： | 为了降低隧道爆破施工时粉尘的浓度,改善劳动者作业环境,选用多种基料、表面活性剂等,通过润湿性试验、表面张力试验和降毒性试验,确定了新型水炮泥降尘剂的配方,即基料选氯化钠,表面活性剂选十二烷基苯磺酸钠,添加剂为氯化铵和硫酸铜;为了验证新型水炮泥降尘剂的降尘效果,设计了水炮泥现场装填方案,并进行了现场对比试验,试验结果表明:加入水炮泥爆破全尘降尘率可达48%以上,比现有的通风除尘措施有了较大的提高。

| Abstract: | In order to reduce the dust concentration of tunnel blasting ,improve the working environment ,a number of base materials and surface- active agents are adopted in the experiment .By measuring the surface tension of the solution ,pow-der forward osmosis method and determination of toxicity reduction of nitrogen oxides ,the basic material of water stemming dustfall agent is determined ,that is ,the base material is sodium chloride ,surface- active agents is dodecyl benzene sul-fonic acid sodium and additives for ammonium chloride and copper sulfate .In order to verify the new water stemming dustfall effect ,the specific fill scheme is determined ,the field comparison tests are conducted and the results show that the average removal efficiency on all size dust reaches up to 48% ,when the new water stemming blasting dust is used and it has been greatly improved compared with the traditional ventilation and dust -collecting measures . |
