Research on Separating Technology for Fire Area in the Boundary of Bandingliangta Coal Mine

For the high temperature fire area in Zhujiagou open-pit stripping mined-out area in the boundary of Bandingliangta Coal Mine, through the analysis of actual situation of mine geological data and high temperature fire zone, it is determined that ground drillings are carried out in the boundary of Bandingliangta Coal Mine. Through pouring plastic water glass gel material through drilling hole to construct a separating wall for fire area in the boundary of Bandingliangta Coal Mine, it effectively prevents the fire in Zhujiagou open-pit stripping and digging out zone to spread to Bandingliangta Coal Mine.
