ABSTRACT:
An inflatable hour glass shaped rubber plug is placed in blasting holes immediately after they are drilled. This plug prevents unwanted debris from entering drilled holes, during idle periods. Thus it will allow necessary space for blasting agents, resulting in a greater shattered blast, and level roadbed conditions. As a direct result, it will increase production in loading and haulage equipment, and lower maintenance cost and mining operation cost overall.
