Block sinking mining method comprising, digging undercut tunnels, drilling undercut blast holes through the undercut tunnel roofs and placing and detonating explosive charges in those holes to fly rocks over the undercut tunnels, digging Tunnels at the extraction level at an extraction level below the undercut level.
Vibratory pulse generator system to reduce the effective friction between a pipe and a well, when it is inserted into the well, comprising: a hydraulic switch that has a first and a second feed circuit, a piston, and a shut-off valve ; hydraulic switch, and method to generate a periodic impulse.
METHOD FOR MONITORING THE DEPLOYMENT OF MINERAL DURING MINING OPERATIONS OF BLOCK SOCAVATIONS THAT INCLUDES INTRODUCING AN ACTIVE MAGNETIC TRANSPONDER, GENERATING A MAGNETIC SIGNAL, REMOTELY MONITORING THE MAGNETIC FIELD WITH A MAG
