METHOD FOR RESEARCHING STABILITY OF DUMPS Russian patent published in 2004 - IPC

FIELD: mining industry.

SUBSTANCE: method includes mounting of anchor system in base of dump before its fill, said system having four posts and rigidity beams mounted perpendicularly to posts with possible vertical displacement along them. To first pair of beams on both sides vertical stops are mounted with struts and loading devices, as well as trolleys with loading devices. To second pair of beams on both sides loading devices are mounted at different values of slanting angle to beams or slanting angle to horizontal plane. In places of mounting of vertical supports horizontal areas are cleared, and prisms of dump rocks are contoured. On prisms at top sections metallic cases are placed, stamps are mounted as well as loading devices on the top and on the side for providing for compressing and displacing forces. By means of loading devices loads are transferred onto dump rocks and necessary measurements of parameters of rocks displacements are performed, as well as of respective forces created by loading devices, after which on basis of received experimental data hardness parameters of dump rocks are determined.

EFFECT: reliable and effective researching of stability parameters of dumps.
