Cast blasting has received a renewed interest in the past few years, especially in surface coal mines. The true spacing-to-burden relationship, shot timing, and explosive used will all affect overburden movement and breakage. The aim of constructing safety is to prove that the system possesses the highest safety integrity level. Industry. The domestic consumption of explosives and blasting agents during the year 2002 was about 5.53 billion pounds. <>

Regardless of how well the machinery or methods are designed, there will always be potential for serious accidents. Presented By 4, 2015.D. �X�,�;���
The detonation sequence of the holes can cause these measurements to change. <>
Assess probability (likelihood) for hazardous events. [Accessed 13 08 In order to improve safety and mine more economically, a Shibpur The blaster can use these tools to adjust borehole loading to match site conditions.Understanding the mechanics of blasting and its relationship to the mining operation as a whole underlie the most successful blasting programs. Mine workers should be trained on the hazards of over-exposure to coal … Captive key systems; scanners and a GroundProbe slope stability radar (SSR). Evaluate the risks associated with each hazard. Opinions vary regarding the proper selection of these variables for specific purposes. 4 0 obj
The An experienced driller could detect potential problem areas such as voids, mud seams, incompetent rocks, and other irregularities by observing the progress of drilling. The principles of cast blasting may be used to open a key along the new highwall, improve productivity of truck operati, ons, and help directional spoil movement in special applications. "�=]�� ��� My journey has been an Interesting one and it’s hard to believe that I am now in my third decade in this mining business! The extent to which the risk of exposure must be controlled is to a level that which is “reasonably practicable”.
