Рассмотрены направления повышения эффективности мероприятий по разгрузке массива от повышенных напряжений бурением разгрузочных скважин. Приведены основные этапы реализации данного способа на удароопасных рудниках Талнахского рудного узла и обозначены основные проблемы и недостатки, которые ограничивали область его применения. Отмечено отсутствие инженерной методики расчета шага бурения разгрузочных скважин. Об основаны положения такой методики, которые учитывают ключевые особенности геомеханической системы скважина–целик. Показан подход к определению критических напряжений, при превышении которых должна происходить деформация межскважинного целика. Разработанная методика позволяет определить ширину межскважинного целика в зависимости от диаметра скважин, прочности массива и степени нарушенности руды.
