Limestone Sampling and Testing Cement and Lime Mines -

2021-8-14  Sampling of the initial heading is usually done by taking samples of the top, middle and bottom of the mine face. This is performed after the heading is cleaned out and scaling has removed any loose stone from the top and face. Bench sampling can be done using the same method as the open pit quarry using the rotary air drill chip samples.

Pillar Strength and Design Methodology for Stone Mines

2012-8-30  Underground stone mines in the United States make use of the room-and-pillar method of mining. A prerequisite for a safe working environment is that the pillars should adequately support the overburden and the pillar ribs and rooms should remain stable during mining. At present pillar dimensions are either based on experience at neighboring mines or on strength equations that were developed for metal or non-metal mines. This paper presents a pillar design methodology that was developed from a study of pillar performance in operating stone mines. Data were collected that describe the rock mass quality, pillar conditions, mining dimensions and intact rock strength.The results showed that current mining practices have resulted in generally stable pillar layouts with no recent cases of extensive pillar
