(54) СПОСОБ УКРЕПЛЕНИЯ УСТУПОВ НА КАРЬЕРАХ(54) METHOD OF STRENGTHENING ACCESS ON CAREERS
1one
Изобретение относитс к горной промышленности и может быть использовано при открытой разработке месторождений полезных ископаемых.The invention relates to the mining industry and can be used in the open pit mining of mineral deposits.
Известен способ укреплени уступов на карьерах, включающий проведение подземных горных выработок и укрепление массива из выработок 1.There is a method of strengthening the ledges in quarries, including the conduct of underground mine workings and the strengthening of the array of workings 1.
Известен также способ укреплени уступов на карьерах, включающий проведение подземных выработок, бурение из них скважин до выхода на поверхность откоса, установку в скважинах и подземных выработках канатов и закрепление их концов на поверхности откосов и в расположенных за плоскостью сдвижени массива замках подземных выработок с нат жение.м канатов 2.There is also known a method of strengthening the ledges in quarries, including carrying out underground workings, drilling wells from them before reaching the surface of the slope, installing ropes in the wells and underground workings and fixing their ends on the slope surface and underground workings located behind the displacement plane .m ropes 2.
Однако данный способ характеризуетс недостаточно большими углами бортов карьеров в предельном положении и значительными затратами на укрепление.However, this method is characterized by insufficiently large pit angles of the quarries in the limiting position and significant strengthening costs.
Цель изобретени - увеличение углов бортов карьеров в предельном положении и уменьшение затрат на укрепление.The purpose of the invention is to increase the angles of the pit walls in the ultimate position and reduce the cost of strengthening.
Поставленна цель достигаетс тем, что скважины бур т из штолен, которые проход т со стороны откосов уступов.The goal is achieved by the fact that wells are drilled from tunnels that pass from the side slopes of the benches.
На фиг. 1 представлена обща схема укреплени уступов; на фиг. 2 - схема укреплени в плане.FIG. 1 shows a general scheme for strengthening the ledges; in fig. 2 is a plan for reinforcement scheme.
Способ укреплени уступов на карьерах заключаетс в следующем.The method for strengthening the ledges in quarries is as follows.
При подходе фронта горных работ на закрепл емо.м уступе 1 со стороны откоса проход т штольни 2. Из штолен бур т скважины 3 с выходом их на поверхность откоса уступа. В скважинах и штольне устанавливают канаты 4, которые закрепл ют на поверхности откосов и в замках 5 штольни, расположенных за плоскостью 6 сдвижени массива. У нижней бровки уступа устанавливают металлоконструкцию 7, необходимую дл компенсации усилий, возникающих при нат жении канатов.At the approach of the mining front, an adit 2. is passed on a fixed ledge 1 on the side of the slope. From the tunnels, a well 3 is drilled to the surface of the escarpment slope. In the wells and the tunnel, ropes 4 are installed, which are fixed on the surface of the slopes and in the castles 5 of the tunnel, located behind the plane 6 of the displacement of the massif. At the lower edge of the ledge, a metal structure 7 is installed, which is necessary to compensate for the stresses caused by the tension of the ropes.
Предлагаемый способ позвол ет увеличить углы бортов карьеров в peдeльнoм положении и снизить затраты на укрепление .The proposed method makes it possible to increase the pit angles of the quarries in a different position and reduce the costs of reinforcement.
