【Abstract】 Based on the combination of theory and engineering practice, the influencing factors on slope stability in chamber blasting are analyzed, and the technical measures on safeguarding slope stability in chamber blasting are given from aspects of blasting design and construction, that are direction change of blasting effect, power reduction of blasting on the pot of high slope, adoption of muster charge instead of disperse charge, control of maximum dosage for batch blasting, forbidding crack developing with excavating step, avoidance of crack formation outside the slope by use of range groove, slope control with pre-blasting.更多还原
