Description

Известные способы борьбы с пуче111 ел подземных горпых выработок , состо щие в устройстве мощной монолитной крепи в выработках, систематической поддирке почвы, анкеровании почвы и т. д., не решают полностью задачи предотвращени  вспучивани  окружающих подземные выработки пород, требуют значительных затрат средств и рабочей силы.Known methods of dealing with the bundle 111 ate underground underground workings, consisting in the installation of powerful monolithic supports in the workings, systematic underfilling of the soil, anchoring of the soil, etc., do not completely solve the problem of preventing the swelling of the surrounding underground workings of rocks, require significant expenditures and labor .

Дл  борьбы с пучением в подземных выработках и в особенности дл  борьбы с поддуванием почвы выработок предлагаетс  способ уплотнени  пород в зоне их пластического течени  при помощи подземных взрывов - камуфлетов. Созданные взрывами сосредоточенных и удлиненных зар дов взрывчатых веществ камуфлетные полости привод т к уплотнению пород в зоне их пластического течени , а следовательно, и к изменению их физико-механических свойств: увеличению угла внутреннего трени  и коэффициента сцеплени  породы.To combat heaving in underground workings, and especially to combat the blowing of soil, the workings offer a method of compacting rocks in the area of their plastic flow with the help of underground explosions — camouflets. The camouflet cavities created by explosions of concentrated and elongated explosives lead to compaction of rocks in the area of their plastic flow and, consequently, to a change in their physicomechanical properties: an increase in the angle of internal friction and the coefficient of adhesion of the rock.

Уплотнение породы взрывами потребует значительно больщих давлений дл  вснучивани  породы вокруг подземной выработки и в больщинстве случаев предотвращает пучение. Предлагаемый способ не требует больщих затрат рабочей силы н во много раз экономичнее известных .Compaction of the rock by explosions will require significantly greater pressure for the sounding of the rock around the underground and in most cases prevents swelling. The proposed method does not require large labor costs and many times more economically known.

На чертеже показано расположение зар дов в почве выработки дл  образовани  камуфлетных полостей.The drawing shows the location of charges in the soil of the mine for the formation of camouflet cavities.

Камуфлетные полости 1 создаютс  на контакте основных плоскостей сдвига 2 породных клиньев 5. Дл  образовани  камуфлетной полости взрывом сосредоточенного зар да в подощве выработки 4 пробуривают вертикальный или наклонный щпур 5, в который укладывают зар д взрывчатого вещества 6, взрываемый после тщательной забойки.Camouflage cavities 1 are created on the contact of the main shear planes of 2 rock wedges 5. To form a camouflage cavity by an explosion of a concentrated charge in the basement 4, a vertical or inclined drill 5 is drilled into which explosive charge 6 is blown up after careful tamping.

Дл  образовани  камуфлетной полости взрывом удлиненного зар да пробуривают соответственно наклонные или горизонтальные щпуры.For the formation of a camouflage cavity by the explosion of an elongated charge, respectively, inclined or horizontal drill holes are drilled.
