    Explosives being used in mining. Drill and blast mining is a common method used to break up 'benches' of rock in order to send the smaller pieces of rock containing ore to the processing plant to further separate the valuable ore from the waste rock. As the name suggests, holes are drilled into a section of rock – either above or below ground

    Jun 10, 2015 Stemming is a material that is put inside of a blast hole to help prevent gases from escaping. While stemming is typically put in the top of a blast hole, it can also be used to help bridge mud seams or weak layers. Improperly placed stemming can greater decrease fragmentation size. This is because if a stronger layer is stemmed that means
