The research allows to introduce into the mining process is the use of a blasting agent low velocity of detonation VOD (velocity of detonation) with the purpose improve the blasting parameters in the production of anthracite coal and hence reduce unitary costs drilling and blasting. It presents detail the processing and analysis of data using analysis before and after the use agent blasting, whose indicators are borehole pressure, fragmentation and costs; to determinate if there are differences the statistical prove t-student was used, with a significance level 5%. Finally, we present the results about the blasting parameters, leading to conclude that it is feasible to use a blasting agent that substantially improves fragmentation and reduce mining costs.
