Effect of blasting pattern design on rock mass stability in mineral mining

By coupling mining and fundamental sciences, the cause-and-effect relationships between mining technologies, rock mass stability and blasting pattern designs are discussed. One of the aspects of further advancement in the proposed conceptual approach to problem solution in mining practice is connected with interaction between rock mass stability factors, on the one hand, and blasting, on the other hand. The approach is based on the study into the solely effect of blasting on the stress state of rock mass by means of the analysis of various technological aspects and their use for the purpose of safe and efficient mineral mining. The newly proposed technique of blasting in multiple intervals in drillholes mitigates aggravating impact on rock mass. The scientific novelty lies in the modern-level methodology developed to solve the specified relevant problem using appropriate science and technology. Efficiency of the new scientific-and-technical trend in the mining science is confirmed.
