Study on engineering practice of forced caving using presplitting blasting
Combined with forced roof caving technology using pre-splitting and blasting methods with deep or shallow borehole, this research illustrates the construction environment and implementation methods in detail, analyzes implementation effect and strata behaviors of working face at the length, and discusses the features and adaptive conditions of forced roof caving technology with pre-splitting and blasting at close range, which has a certain directive significance and reference value to engineering practices with similar conditions.
