【摘要】：根据地下金属矿山矿房爆破后出矿时粉尘浓度大、持续时间长的特点,通过分析现阶段喷雾降尘方法存在缺点和不足的原因,提出利用高压降尘喷枪将降尘水直接作用于产尘源,从粉尘产生的源头上降低爆破后和出矿时的粉尘浓度。根据这一思路,设计制作了适用于地下金属矿山的降尘喷枪,通过传粉尘浓度感器控制降尘喷枪的开启,使降尘过程实现自动化。目前该技术已经在会宝岭铁矿现场进行了应用,较常规水幕降尘方法,可将爆破后等待炮烟时间缩短60%以上,可降低出矿巷道内粉尘浓度75%以上,降低上水平回风巷道内粉尘浓度60%以上。
[Abstract]:According to the characteristics of large dust concentration and long duration after blasting in underground metal mines, this paper analyzes the shortcomings and shortcomings of the present spray dust control method. It is proposed that the dust fall water can be directly applied to the source of dust production by using the high pressure dust fall spray gun to reduce the dust concentration after blasting and at the time of mining from the source of dust production. The dust spray gun suitable for underground metal mine is designed and manufactured. The dust concentration sensor is used to control the opening of dust fall spray gun. At present, the technology has been applied in the field of Huibao Ling Iron Mine. Compared with the conventional water curtain dust control method, the waiting time after blasting can be reduced by more than 60%. The dust concentration in the roadway can be reduced by more than 75%, and the dust concentration in the upper level return air tunnel by more than 60%.
