Abstract

Изобретение относится к горной промышленности, может быть использовано при сооружении горизонтальных и наклонных горных выработок. Цель изобретения - снижение стоимости и трудоемкости работ по предотвращению пучения почвы. В почву горной выработки бурят разгрузочные шпуры на отдельной заходке. Заряжают их зарядами взрывчатых веществ и производят взрывание, обеспечивая выброс 20-30% объема разрушенной породы в выработку. Затем породу выброса убирают до проектной отметки почвы и производят упрочнение разгруженных от напряжений пород посредством заливки в пустоты скрепляющего раствора. Для равномерного и качественного распространения скрепляющего раствора по всей глубине взорванной заходки на поверхности почвы устанавливают виброплощадку и осуществляют поверхностное вибрирование взорванных пород. Заливку и вибрирование следует производить вплоть до изливания раствора на поверхности почвы всей заходки.The invention relates to the mining industry, can be used in the construction of horizontal and inclined mine workings. The purpose of the invention is to reduce the cost and labor intensity of work to prevent soil heaving. Unloading holes are drilled into the soil of a mine working on a separate entry. They are charged with explosive charges and detonated, ensuring the release of 20-30% of the volume of the destroyed rock into the mine. Then, the ejection rock is removed to the design level of the soil and the stress-relieved rocks are hardened by pouring a fastening solution into the voids. For uniform and high-quality distribution of the bonding solution over the entire depth of the blasted entry, a vibrating platform is installed on the soil surface and surface vibration of the blasted rocks is carried out. Pouring and vibrating should be carried out up to pouring the solution onto the soil surface of the entire entry.
