Development of a multiple level underground

2020-1-1  The room-and-pillar mining method with secondary floor recovery utilized within the stone mining industry results in slender pillar geometry. As the limestone pillar is loaded, the brittle nature of the rock lends itself to a significant strength reduction post-yield . The behavior of the rock pillar coupled with slender geometry results in pillar spalling, referred to as “hour-glassing”.

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.
