Abstract
The objective was to determine to what extent geology, mainly structure, influenced blasting practices and results in limestone and dolomite quarries, and to ascertain how geologic features could be utilized to advantage in quarrying. The rock in the quarries visited was mined by bench blasting with long cylindrical charges in vertical boreholes. The gross geologic features observed to influence blasting are: horizontal bedding without conspicuous jointing, horizontal bedding with conspicuous jointing, and folds, faults, unconformities, caves, and filled joints.
