Abstract
1. Способ разрушения горных пород в подземных условиях, заключающихся в бурении из забоя горной выработки шпуров и размещении в них зарядов ВВ, бурении разгрузочных скважин, подрыве этих зарядов ВВ, отличающийся тем, что в забое, по длине или в устье одной или нескольких разгрузочных скважин устанавливают дополнительно сосредоточенные заряды ВВ и проводят их подрыв одновременно с подрывом зарядов ВВ в основных шпурах.2. Способ по п.1, отличающийся тем, что подрыв дополнительных зарядов проводят с задержкой по отношению к подрыву основных зарядов, причем время задержки определяют расчетно-экспериментальным методом.3. Способ по п.1, отличающийся тем, что подрыв дополнительных зарядов проводят ранее подрыва основных зарядов, причем время опережения определяют расчетно-экспериментальным методом.4. Способ по п.1, отличающийся тем, что в разгрузочных скважинах устанавливают пробки, размер которых и места установки определяют расчетно-экспериментальным методом.1. The method of destruction of rocks in underground conditions, consisting in drilling from the bottom of the mine working holes and placing explosive charges in them, drilling unloading wells, blasting these explosive charges, characterized in that in the face, along the length or in the mouth of one or more discharge wells set additionally concentrated explosive charges and carry out their undermining simultaneously with the detonation of explosive charges in the main holes. 2. The method according to claim 1, characterized in that the undermining of the additional charges is carried out with a delay in relation to the undermining of the main charges, the delay time being determined by the calculation-experimental method. The method according to claim 1, characterized in that the blasting of the additional charges is carried out earlier than the blasting of the main charges, the lead time being determined by the calculation-experimental method. The method according to claim 1, characterized in that plugs are installed in the discharge wells, the size of which and the installation location are determined by the calculation-experimental method.
