Definitions
- the invention relates to a method of disintegrating rock by synergism of melting and water streams and it is designed to be used especially in the drilling process, particularly of hard rocks.
- Phreatomagmatic explosions of rhyolitic magma A. Austin-Erickson, R. Buttner, P. Dellino, M. H. Ort, B. Zimanowski, Phreatomagmatic explosions of rhyolitic magma: Experimental and field evidence, JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 1 13, B11201 , 12 PP., 2008.
- Patents related to the given field US 6319434, US 5667147, US 6660223, US 2533633, US 3594142, US 4286647, US 6349548, US 5987899 are related to interaction of melt and water for production of fine granules or powders.
- the aim of the present invention is to increase the efficiency of drilling process considerably, particularly of hard rocks, as process of synergism of thermal processes and water action.
- the aim of the present invention is utilization of thermal processes with synergism of water and with utilization of conversion of thermal energy into kinetic energy of particles of disintegrated rock in the drilling process, particularly of hard rocks, in order to increase efficiency of drilling process.
- the heat or energy flow source acts on the rock at least until its local phase transition into the melt occurs
- the water stream is interrupted in dependence on heat balance of heating process and in the time of realization of rock heating process by the energy flow.
- the eccentric flow of particles empties the action area of the heat flow, and the disintegrated rock by melting and by synergism of the water streams and prepares it for new action of the heat flow.
- the water streams are directed into one direction or they are directed parallely with the direction of the heat flow action or they are directed tangentially around the area of the heat flow action or they are directed eccentrically from the area of the heat flow action, so that they disintegrate the rock by synergism of the water streams and local acting of heat flow, until phase transition of it into the melt occurs.
- the action of the water streams, which act on the created melt along one side or from all sides of the created melt, is being interrupted in dependence on heat balance of heating process causing melting of the rock.
- the sphere of action extends into the depth of the rock.
- the sphere of action extends sideways next to the original area.
- Main advantage of solution according to the present invention is increasing the efficiency of drilling processes, particularly of hard rocks.
- Fig. 1 shows the device consisting of the heat flow source 1, which produces the thermal plasma flow 2.
- the plasma flow acts on the rock 3 and on its surface melts the rock into the melt 4. After some time, the water stream 6 is injected into the melt 4 by nozzle 5.
- Fig. 2 shows a state after injecting water stream 6 into the melt 4, where the explosive flow of the fragmented particles of melt 7 is formed, and the particles convert into the solid phase again and fly away from the area of interaction of the water stream 6 and the melt 4.
- the stream of particles of melt 7 has kinetic energy from the heat energy supplied to the melt 4.
