Blasting is an integral part of surface mining operations. To uncover coal reserves, the rocks overlying the coal are broken with explosives and excavated with various types of large earth-moving equipment. Without blasting, a vital part of the nation's energy reserve would be inaccessible. Blast site with drilling and earth moving equipment.

General blasting jobs that are small in populated areas can run up costs with services of drills, mats, and the cost of nitro-based explosives during winter months. Combo that with the costs of a pre-blast survey and it can make rock removal not efficient. Often the best solution is to use an oversize machine with a breaker.
