A method for forming gas-absorbing plugging of downhole and pile charges includes sequentially inserting a gas-absorbing element and a layer of available bulk material into the well. The gasabsorbing element consists of a sealing gas-absorbing layer and a gas-absorbing layer. First, the sealing gas-absorbing layer is placed in the well, and the gas-absorbing layer is placed directly on top of it, above which the available bulk material is placed. The sealing gas-absorbing layer is a mixture of slaked lime Ca(OH)2, which is a thick suspension, and a thickener in the form of sodium silicate Na2SiO3, which, when mixed, forms calcium silicate and sodium hydroxide. The gasabsorbing layer is made of hydrated lime Ca(OH)2 in the form of a thick suspension. Before pouring slaked lime, its volume is calculated depending on the parameters of the well and the type of explosive.
The utility model relates to methods of blasting operations by mining enterprises and construction companies using borehole or blast-hole charges that require plugging. In most cases, the method of driving downhole or blast-hole charges involves the use of mining waste or crushed stone or concrete as driving material, and the task of which is to lock the explosion products and direct the explosion energy to the destruction of the corresponding object, for example, a rock mass or a construction object during its demolition.
