摘要： The method is used in ore mining and in the mining industry,for the conservation of wastes, etc. By it the rock massif inwhich the galleries and shafts are driven or sunk returns to itsnatural filtration state and the waters filtrating across it havethe same quantities and concentrations of pollutants which existedbefore the works had been carried out. The pollutants contained inthe water reduces in the course of time. The ecological state ofthe district is restored without any need for building expensivewater treatmetn stations of large water quantities, as weel as tobury chemical and/or radioactive wastes from the dressing. Themethod consists in closing the outlet of every gallery or shaft bya water impermeable partition after the operation is over.Additional water tight barriers, antifiltration linings with waterimpermeable partitions and facings are made in the places wherethe shafts are sunk and the galleries driven and which have higherfiltration coefficient than the average for the massif.1 claim

摘要： The device and the system are used in measuring and control systems for the measurement and monitoring of the full porous pressure, the hydrodynamic pressure and the level of the depression curve in dams, slurry ponds, slag heaps, slime ponds, landslides, monitoring boreholes and other systems applied in the hydraulic engineering. They are used for the measurement, memory storage and transmission all changes in the pressure, regardless of the reasons causing it. The device (1) includes a sensor for pressure measurement (2) fitted in a piezometric tube (8) connected by its upper end to a metal box (10) in which memory device (5) and the transceiver unit (6) are mounted, power supplied by storage batteries (7). The piezometric tube (8) has lightening protection (9). In the tube (8) more than one sensor are fitted for measuring the pressure (2), each of which is coupled by its cable (3) to an analysis and control unit (4) in which the timer is built-in. Above the analysis and control unit (4) the memory storage device (5) and the data transmitter executed in the form of a transceiver unit (6) are fitted. The system includes means for measuring the pressure, representing n-number of devices for measuring the level of the depression curve (16), n-number of devices for measuring the hydrodynamic pressure (17), n-number of devices for measuring the porous pressure (18) and n-number of devices for measuring full pressure (19) One each of every measuring device (16, 17, 18 and 19) is grouped in a module. Each module is assembled at the intersection points between inter-perpendicular profiles (20) and rows (21), conventionally formed in body (22) on the wall. Each of the measuring devices (16, 17, 18 and 19) of the module is coupled to a transceiver module (12) of the receiving station. 4 claims, 6 figures

摘要： The method and the plant are used for the treatment of waste waters, in particular of chemically or radioactively contaminated waters from the settling tanks of tailing ponds, slurry sumps and other waste material depots. They help in the materialization of ecological and low-energy consuming treatment of any quantities of any partially treated waste waters, to be discharged into the water intake. By the method preheating of the waste waters is performed, after which it is fed under pressure, sprayed over vertical rectangular frames (1) and is discharged into a collection chute (15). The heated water, by continuous pouring over the rectangular frames in the form of evaporation panels (1) is evaporated, the evaporation being regulated by simultaneous control of the parameters of temperature, humidity and air pressure. The plant includes a structure (28) with solar ray capturing walls in the form of a hothouse (25). In the hothouse interior (25) vertical rectangular frames are mounted, above which, by means of a tubular system (6) with a pump (7), sprayer nozzles (5) are mounted, and below them a collection chute (15) and a heating tank (8) with a heat exchanger (9) are fitted. The vertical rectangular frames are in the form of evaporation panels (1) mounted in rows in length and in width, each panel (1) being bounded to a protection apron (2) and a protection chute bottom (3), mounted in an inclined chute (16), each of which end in the common chute (15), restricted among the panels (1) by passages (22) Tank (8) is connected to a solar collector (11), and behind each of the rows of panels (1) , in length, behind a protection plate (23) a pressing device (26) is fitted. In the upper part of the walls, temperature sensors (29), humidity sensors (30) and a pressure sensors (31) are installed, connected to a control computer (32). In the roofing part upper ventilation flaps (19) and sidewall ventilation flaps (18) are found, connected by fans (20). 4 claims, 3 figures

摘要： The device is used basically in hydraulic engineering, and in particular in instrumentation systems. It operates autonomously, by cableless storing and transmitting the collected information, being reliably protected against lightnings and mechnical damage during subsidence of the layers in which it is mounted, and can be repaired in case of damage. The device consists of a pressure sensor, connected with cable, and of an instrumentation station where there is a switching and recording device. Sensor (1) for electronic reading pressure measurement and for transmission of the data from the measurements is connected by cable (2) to a memory unit (3) which is connected to a transmitter (8) and receiver (9) with a recording device fitted in the instrumentation station. Sensor (1) is automatically switched by a time device (4) which has an earth tremor sensor (5) and is connected to sensor (1) by cable (9). The electric supply is by using storage batteries (7).
