Description
крытию которых способствовало взрывание зар дов первой очереди. Аналогично производ т взрывание остальных зар дов по контуру выработки. Таким образом, нагнетание в прилегающий массив твердеющих составов производитс отдельными порци ми одновременно с создание экранирующей зоны.the cover of which was promoted by blasting charges of the first stage. Similarly, the blasting of the remaining charges along the production contour is carried out. Thus, the injection into the adjacent array of hardening compositions is carried out in separate portions simultaneously with the creation of a shielding zone.
