Sublevel Open Stoping originated in the early 1900’s in iron ore mines in Michigan, USA It was developed over the years from a method originally known as short hole bench and train miningGenerally a large scale open stoping method, it is often referred to as long hole or blast hole stopingIn sublevel stoping, the holes are generally just a few meters apart and some of the holes are adjacent to both the foot wall and the hanging wall If deviation occurs, it causes a decrease in ore recovery, an increased amount of dilution, and less homogenous fragmentation In the Sublevel stoping WassaraThe quarry is in operation since 1927: at present, the exploitation is carried out completely underground by sublevel stoping The exploitation Involves two levels, with 4 rooms at the upper level, and 9 rooms at the lower levelDesign criteria for production blasting in an Sublevel Stoping 15 Cutandfill Stoping 16 Longwall Mining 17 Sublevel Caving 18 Block Caving 2 Underground Mining Machinery Glossary Bibliography Biographical Sketches Summary The first section gives an overview of underg round mining methods and practices as used commonly in underground mines, including classification of underground Underground Mining Methods and Equipment109 Sublevel stoping at Olympic Dam 115 Improved results at Feb 13, 2014 stoping equipment in underground platinum minesrock crushing equipment for gold mining mineral processing One or more engineers will be dispatched to the quarry site to help install the customers’ plantsstoping equipment in underground platinum mines
