Analysis of Mining Subsidence on Mining Damage of Fly Ash Belt Transport Corridor

In view of the problem that mining subsidence damage to the belt transport corridor of fly ash in power plant, taking the actual mining project in 22618 working face of Zhenchengdi Coal Mine as an example, 13 monitoring points were set up on the basis of the support of the belt transport corridor above it for deformation monitoring. Based on the measured data and the structural characteristics of the belt conveyor corridor, the mining damage to the belt conveyor corridor of fly ash in power plant caused by surface mining subsidence was analyzed. The measures to mitigate the mining damage in the belt transportation corridor from both underground and ground were given in the paper.
