ABSTRACT
There are several underground mines in India which operate in close proximity to an operating surface mines. Under such working conditions, there exists an immense danger to the safety and stability of underground mine openings and various underground structures viz. coal pillars, roof, water dams, ventilation and isolation stoppings situated in close proximity to operating surface mines. The prediction of the peak vibration level normally measured by Peak Particle Velocity (PPV) at the various underground structures caused by neighbouring surface mine blasting is pivotal for the safety of underground structures in terms of pillar spalling, roof collapse and junction failure. In addition, the prediction of vibration will help the surface mine operators to carry out optimum size controlled surface blasting with regard to the safety of the underground mine structures.
