Abstract:

Abstract: large cross section vertical coal bunker in the construction process, the construction technology and field management of labor organization and more complicated, thus the construction efficiency and the safety coefficient is low. In order to solve the technical problem of construction, the military city in large cross section coal bunker in coal mine construction process, according to the mine construction technology conditions, with reference to the relevant literature, highlights from the bunker construction efficiency, safety and proceed with of bunker, excavation, support process and the labor organization and management are discussed. Research results show that: the coal bunker construction process and site optimization of labor organization adjustment, the construction efficiency is improved by more than 30%; by strengthening the construction site safety management, for the construction of the main safe hidden trouble to take effective measures, ensure construction safety.
