Research and application of comprehensive control technology for floor heaving in soft rock roadway
ZHANG Jian-lin
Abstract：In order to control the roadway floor heaving in Yuxi Coal Mine, the comprehensive control technology for soft rocL roadway floor heaving is proposed through deep research, analysis and comparison, using a combined floor heaving control technology comprising pre-stressed full length grouting anchor cable, rebar cage, rebar ladder girder and concrete pouring. According to the results of field engineering practice, favorable floor heaving control effect has been achieved using the proposed technology.
