Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking).
Bochni. Nadmierne rozługowania wodą pod nieizolowanym stropem calizn doprowadziły tam do zapadlisk terenu wypełnionych solanką. Obecnie w wysadach solnych, w Górze koło Inowrocławia i w Mogilnie, na głębokościach od 400 m do 1700 m, pozyskuje się roztwory soli metodą otworową.

Borehole mining is a general term for any process in which the wanted mineral or metal values of a deposit are fluidized in place by some means and removed from the deposit via borehole.
21 sty 2023 · The hydro-mining technology is considered as a promising method of bituminous coal excavation. The paper presents the results of the in-situ experimental campaign and modelling of hydro-cutting...
15 maj 2022 · Introduction. Drill and blast is the main excavation method used in mining, being the most economical mean to break and fragment rocks, especially hard rocks [1]. It consists in drilling boreholes into the ground, charging them with explosives, and blasting them to fragment and throw the rock mass.
