多层岩盐矿（含芒硝矿）的开采，普遍采用分层建井回采工艺，即每回采一层盐，均需分别建一组回采井，回采费用高。该文介绍一种新的回采工艺——爆破切割全程裸露盐层，其特点是建一组回采井，采用爆破切割方法，将所有盐层裸露并予以回采，大大降低回采费用，提高回采速度。 Multi-layer rock salt mine (including mirabilite) mining, commonly used stratified mining recovery process, that is, each layer of salt recovery, are required to build a group of recovery wells, high cost of recovery. This paper introduces a new mining technology - blasting and cutting the entire exposed salt layer, which is characterized by a set of recovery wells, using blasting and cutting method to expose and reclaim all salt layers, greatly reducing the recovery cost and increasing the recovery rate.
