Combining with the characteristic of loading field,researchers invent the curing dentin binding agent,which be sprayed on the bulk granular freight,can form a continuous and firm cured layer on the surface of bulk granular freight having a remarkable effect of dust-suppression and splash-preventing.

In order to improve coal mine traditional mode of fireproof and dust-suppression,brought forward two applications through analyzing fireproofing dust-depressor's mechanisms and mensurating its performance in the laboratory.

In this article,the dust pollution is effectively controlled by installation of walls for preventing the wind and restraining the dust around the stocking yard to decrease the wind speed consequently inside the stocking yard.

By using the large-area blower, this paper tests the wind-proof effect of butterfly-type wind-proof and dust-control net under natural condition, and based on the test results, points out that the butterfly-like wind-proof and dust-control net, which can get the ideal wind-proof and dust-control effect, can make 5 degree wind speed drop to 1 and 12 degree to 3.
