Description
Изобретение относитс к буровзрывны работам и может использоватьс дл разработки грунта, профилированных выемок , добычи полезных ископаемых и т.п.The invention relates to drilling and blasting operations and can be used for excavation, profiled excavations, mining, etc.
Известны способы отбойки, полезных ископаемых с помощью буровзрывных работ , включающие бурение шпуров или скважин , их зар жание взрывчатым веществом и взрывание ll , Недостатком их вл етс переизмельчение пород и увеличенна зона разброса взорванной массы.Known methods of blasting, minerals using drilling and blasting operations, including drilling holes or wells, their loading with an explosive and blasting ll, they have the disadvantage of over-grinding rocks and an increased area of spread of the exploded mass.
Наиболееблизким техническим решением к предлагаемому изобретению вл етс способ, в котором с учетом сопротивлени массива зар жание произво- . д т смесью мощного и слабого взрывчатых веществ .The closest technical solution to the present invention is a method in which, taking into account the resistance of the array, the charging is produced. d t a mixture of powerful and weak explosives.
Недостатком этого способа вл етс невозможность уменьшени объемной плотности энергии ниже предела, определ в мого наиболее слабым взрывчатым -веществом .The disadvantage of this method is the impossibility of decreasing the bulk energy density below the limit, which is determined by the weakest explosive substance.
Цель изобретени - обеспечить более полное использование энергии взрывчатого вещества путем исключени перезар да шпуров или скважин.The purpose of the invention is to provide a more complete use of the energy of the explosive by eliminating recharge of holes or wells.
Дл этого при зар жании взрывчатым веществом в него ввод т легкий наполнитель , например крошку пёнополистирола.To this end, when charging with an explosive, a lightweight filler is introduced into it, such as foam polystyrene chips.
Отбойку полезных ископаемых производ т следующим образом.The breaking of minerals is carried out as follows.
По горно-геологическим услови м определ ют сетку скважин н бур т их. с помощью устройств, предназначенных дл подачи нескольких сыпучих компонентов производ т зар жание скважик. Такие устройства широко известны в данной области промышленности и их конкретна конструкци не вли ет на существо предложени . В процессе зар жани скважины во взрывчатое вещество ввод т легкий наполнитель , например, 1К ршкуг или гранулы пёнополистирола . Количество введенного наполнител регулируют в соответствии с глубиной скважин, по величине преодлеваемого сопротивлени . Взрывание скважин производ т обычным путем.According to the mining and geological conditions, a grid of wells is drilled. With the help of devices designed to supply several bulk components, a well is charged. Such devices are widely known in the industry and their particular design does not affect the substance of the proposal. In the process of charging a well, a light filler is introduced into the explosive, for example, 1K foam or polystyrene granules. The amount of filler injected is adjusted in accordance with the depth of the well, in terms of the resistance to be overcome. Well blasting is done in the usual way.
