Open publisher page 1 citations

Abstract

Under the confined conditions, one shot shaping of a trench can be ensured as long as the correct blasting parameters are selected, and the linear uncoupling charge and water filling used. In this paper, the selection of blasting parameters, longhole pattern, charge calculation, the making of linear charges and others are introduced in accordance of a feeding pipe engineering in Linyi City of Shandong province.
