Abstract:
For the problem of dust hazard during shaft construction in Hongqingliang Coal Mine, through studying dust characters, producing links, producing dust mechanism of dust sources, dust emission laws and comparison and optimization of dust removal schemes in mine shaft during construction period, we design gas-water two-way spray dust removal technology scheme in shaft excavation of Hongqingliang Coal Mine, which provides safety technology during mine shaft construction period, eliminates hidden dangers of dust, and decreases the occurrence of safety accidents.
