Mineral Mining regulations are based on that work. DMM blasting limits range from 0.75-1.25 inches/second, when based solely on the distance from the blast to the nearest structure.
· Surface blasting breaks up rock and frequently throws rock away from the blast site. Mine workers may be killed or injured by rock thrown by a blast. The blaster who designs a blast determines how far rock from the blast is expected to go.

All mining operations which utilize explosives must have approved Blasting Plans on file in their mining permits. These locations are regulated by the mining divisions of the Department. All other uses of explosives must comply with the "Oklahoma Explosives and Blasting Regulation Act" of Title 63.
The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting
By dynamically tailoring the blast process based on actual, "As-Drilled" hole data, blast processes can achieve higher efficiency and increased fragmentation. The resulting benefits ultimately include less impact on excavators, crushers, grinders, and even more efficient haulage.
PRIMING OF EXPLOSIVES FOR EFFICIENT BLASTING. By: Partha Das Sharma. 1. INTRODUCTION: The massive use of blasting agents such as ANFO, Heavy ANFO etc., in rock breakage has brought about an important development of initiation and priming techniques.
History of Explosives and Blasting In the US and Canada alone, blasters use more than 6 billion pounds of explosives and 75 million detonators per year. Coal mining accounts for two-thirds of consumed explosives of which more than 80% of it is ANFO.
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.
Cast blasting is the controlled placement of overburden into the previously mined cut resulting in a reduced volume or overburden material for the dragline to handle.
· The aim of this new DVD is to provide workers with the critical knowledge on drilling and blasting to aid appreciation of the importance of these mining processes and their related hazards.
