七十年代末至八十年代初,在苏联和国外金属矿山巷道掘进中,进行了借助爆炸能将从液相变为固相的胶结物压入岩层而加固岩层的试验。虽然该法仍处于实验窒和半工业性试验阶段,但现已看出其优点。瑞典首次进行用爆炸能压入胶结物加固岩层的尝试。此法的优点是:可以不用昂贵而不可靠的高压注浆设备;崩矿和加固岩层同步进行,从而提高采矿强度、节省劳力;避免被支护岩层的表面侵蚀和剥落;胶结物
From the late seventies to the early eighties, in the tunneling of metal mines in the Soviet Union and abroad, experiments were carried out to reinforce the rock by pressing the cemented material transformed from the liquid phase into the solid phase by blasting into the rock formation. Although the Act is still in the experimental and semi-industrial pilot phase, its advantages have been identified. For the first time in Sweden, an attempt was made to blast rock layers with cement by blasting. The advantages of this method are: no expensive and unreliable high-pressure grouting equipment can be used; the collapsing and reinforcing strata are carried out synchronously to increase the strength of the mining and labor-saving; the surface erosion and spalling of the strata to be supported are avoided; the cement
