Some limestone limestone quarries in Japan require technical improvements to their mining procedure, especially at steep slopes .<BR>One of the critical concerns in mine scheduling is to define when these steep slopes need to be mined, and to plan how they can be mined safely. <BR>Large equipment can be used to dig the edge of steep slopes, but it must be ensured the safety of the operation and protect against rock block failure.<BR>Blasting may also be used, but it must be controlled to ensure the wall and block stability.<BR>Une mine operation has been using pre-split blasting with ANFO to conform to the design line of the final wall.<BR>This pre-split blasting technique can limit blast energy transmission, reduce vibration and protecting the final wall from the damage of main production blasts.<BR>At the slope side, which is also steep, pre-split blasting techniques will reduce the risk of slope instability and rock mass failure.<BR>However different methods may be required depending on geological structure conditions and mine scheduling requirements.<BR>The author has applied pre-split blasting techniques and combined its usage with large equipment for the steep slope mining.
