The invention relates to a method for forming blasthole stemming for mining, which comprises charging a blasthole with a two-component mixture of resin and catalyst, wherein the two-component mixture produces a stiff foam in situ, and once hardened, the two-component mixture is then detonated. The invention also relates to a system for forming blasthole stemming for mining in order to carry out the method; the mixture used as blasthole stemming for mining that comprises the two-component mixture of resin and catalyst, wherein the resins are based on formaldehyde; and to a method for charging and detonating a mining blasthole by using the two-component mixture.
