Insight into the active roof-contact of cemented paste backfill: A high-efficient expansion material

If the cemented paste backfill (CPB) does not contact the roof, it will cause mining safety problems such as roof collapse, and the passive roof contact technology cannot effectively solve the problem. Therefore, the active roof-contact technology based on expansion agent was developed. The orthogon...
