Description
Изобретение относитс к горной промышленности и может быть использовано при получении каменных заготовок из крепких горных пород.The invention relates to the mining industry and can be used in the preparation of stone billets of hard rock.
Известны способы получени каменных заготовок,включающие бурение по предполагаемой линии раскола шпуров, к стенкам которых прилагаютс нагрузки, обеспечивающие разделение монолита fl .Methods are known for producing stone workpieces, including drilling along an intended line of drilling holes, to the walls of which loads are applied to ensure the separation of the monolith fl.
Наиболее близок к предлагаемому способ получени каменных заготовок с предварительным бурением шпуров, нанесением борозд и нагружением породы в пределах ее упругих деформаций 2j.Closest to the proposed method of obtaining stone workpieces with preliminary drilling of bore-holes, drawing furrows and loading of rock within its elastic deformations 2j.
На фиг. 1 представлена схема размешени шпуров в монолите} на фиг. 2 - нанесение борозд на поверхности шпуров в заданной плоскости раскола.FIG. 1 is a diagram of hole placement in a monolith} in FIG. 2 - drawing the grooves on the surface of the holes in a given plane of the split.
Способ получени каменных заготовок заключаетс в следующем.The method for producing the stone blanks is as follows.
В монолите 1 бур т шпуры 2 по ребрам выкалываемой заготовки на глубину, равную максимальной длине заготовки, а в стенке каждого шпура 2 прорезают борозды 3, обеспечивающие развитие трещин строго во взаимно перпендикул рных плоог кост х.In the monolith 1, the drill holes 2 are along the edges of the workpiece being punctured to a depth equal to the maximum length of the workpiece, and the grooves 3 are cut in the wall of each hole 2, ensuring the development of cracks strictly in mutually perpendicular areas.
