在喷锚支护作业中,水泥和骨料的运输、搅拌以及往喷射机上送料,都产生大量的粉尘;在喷浆的时候,由于压气的扩散,岩面涡流层的流动,混凝土的回弹等也有大量粉尘。高浓度的水泥粉尘,对人体有害,因此,喷锚作业的粉尘问题,是一个急需解决的课题。 1981年以来,我所配合煤炭部组织的攻关,承担了混凝土喷射机除尘器的研究任务,研 In spray anchor support operation, cement and aggregate transportation, mixing and feeding to the jet machine, have a lot of dust; in the shotcrete, due to the spread of pressure, the flow of rock surface turbulence, the rebound of concrete There is also a lot of dust and so on. High concentration of cement dust, harmful to human body, therefore, spray anchor dust operation is an urgent need to solve the problem. Since 1981, with the tackling of the coal ministry organization, I undertook the research task of concrete jet dust remover.
