Abstract: FIELD: mining industry at dust suppression at mass blastings in rocks of any category of strength and degree of water content. SUBSTANCE: the holes are charged in the open cuts with explosives with simultaneous placement in each hole m the upper part of the charge of a sealed shell with water with a diameter of 0.2 to 0.4 of the charge diameter. Suggested also is the placement of the shell lower end in the middle section of the hole charge. At a last of the hole charge water in the shell is subjected to strong compression and changes in the gaseous state. In this state the steam-gas locks the detonation products in the hole and breaks the rock mass. Then, after escapement from the hole, the steam-gas gets expanded, its temperature drops and, as a result of it, water vapors condensate mainly on dust particles. Simultaneously with this process the mechanism of pressure drop inside the dust cloud is realized, which causes its compression by external atmospheric pressure, intensification of the process of dust coagulation and deposition over the point of mass blasting. EFFECT: enhanced efficiency of dust suppression, and enhanced efficiency of explosive energy at mass blastings. 3 cl, 2dwg

Granted: 2003-05-27
Abstract: FIELD: seismology, national systems to monitor and process data of geophysical measurements to forecast earthquakes. SUBSTANCE: measurement channels are spaced apart by distance commensurable with dimensions of earthquake zone. Differential bridge circuit is so balanced that its output resistance in absence of forerunner signal is close to zero and does not exceed voltage of specified threshold of threshold element. With emergence of heavy electrostatic field its value in points of location of spaced-apart meters will markedly differ. Light signal from optical radiation generator will be sent over fiber-optical lines to sensitive elements of electrooptical sensors. Modulated luminous flux is transmitted over fiber-optical line to photodetector which converts optical signal to electric signal. Emergence of sign-forerunner in the form of heavy electrostatic field will lead to unbalance of differential bridge circuit. After some time output voltage of circuit will exceed threshold voltage of element preset by programmable retrieval circuit. Operation of threshold element is determined by service program. EFFECT: increased accuracy, authenticity and timeliness of forecasting. 3 dwg
