Предлагаемое устройство относитс к области определени и исследовани физических параметров горных пород.The proposed device relates to the field of determining and studying the physical parameters of rocks.

Физические параметры горных пород в насто щее врем определ ютс преимущественно в лабораторных услови х с. применением точной аппаратуры. Образцы дл исследовани в лабораторных услови х изготавливаютс из проб, доставленных из шахт, карьеров, рудников и т.п. на камнерезных станках с применением различных эмульсий и жидкостей , отличных по химическому составу от пластовых вод. В лабораторных услови х окружающа образец среда (температура, влажность, давление воздуха и т.п.) всегда отличаетс от параметров воздуха мест залегани горной породы и отбора проО горных пород . Несоответствие параметров сред, через которые проходит сначала проба, а затем и образец до момента испытаний , вызывает значительное изменение естественного состо ни образца (температура , влажность, химический соетав поровой воды и т.п.). это приводит к неточному определению параметров горных пород по исследуемым образцам .Physical parameters of rocks are currently determined predominantly under laboratory conditions. the use of precision equipment. Laboratory samples are made from samples taken from mines, quarries, mines, and the like. on stone-cutting machines with the use of various emulsions and liquids, different in chemical composition from the formation waters. Under laboratory conditions, the surrounding environment of the sample (temperature, humidity, air pressure, etc.) is always different from the parameters of the air in the places where the rock lies and selects the formation of rocks. The discrepancy between the parameters of the media through which the sample first passes, and then the sample before the test, causes a significant change in the natural state of the sample (temperature, humidity, chemical water in the pore water, etc.). This leads to an inaccurate determination of the parameters of rocks by the samples studied.

В предлагаемом устройстве избыточное давление в герметичной емкости в .системе поддержани влажности воздуха создаетс индифферентным газом. Он под давлением подаетс из баллона в герметичную емкость через регул тор давлени . ;In the device according to the invention, an overpressure in an airtight container in an air humidity control system is created by an indifferent gas. It is supplied under pressure from a cylinder to an airtight container through a pressure regulator. ;

Это позвол ет увеличить длительность хранени образцов (проб) горных пород в их естественном состо нии о момента отбора до испытани в лабора торных услови х.This makes it possible to increase the storage time of rock samples (samples) in their natural state from the moment of sampling prior to testing under laboratory conditions.

Па чертеже изображена схема устройства .Pa drawing shows a diagram of the device.

Устройство представл ет собой теплоизол ционный корпус 1, внутри которого размещена герметична емкость 2 со съемной крышкой. Верхн часть 3 теплоизол ционного корпуса выполнена съемной.The device is a heat insulating housing 1, inside of which is placed an airtight container 2 with a removable cover. The upper part 3 of the heat insulating body is removable.

Claims

It contains a thermostat containing an amplifier 4, a bridge 5 of resistances, a temperature indicator 6. Inside the hermetic vessel, spirals 7 are placed across all machines, connected by connector with amplifier 4, wet dry 9 thermal resistances connected by connector to a bridge of resistance, cell 10 with solution and porous substance. Through it passed part of the heating coil. In an airtight container there are shelves 11 with openings on which samples (samples) 12 are placed. In the lower part of the body there is a cylinder 13 with indifferent gas, connected to a pressure-tight pressure regulator 14, and a power source connected to the elements of the thermostat with a connector. The paCoTcieT device is as follows. It is delivered to the production of samples or sampling (mine, quarry, etc.). The preparation of the apparatus is carried out: the upper part 3 of the housing and the lid of the hermetic container 2 are removed. Measure the temperature of the array, the temperature and the humidity of the air adjacent to the array with exemplary instruments. The moisture regulating systems are prepared: a solution of the required concentration is poured into the cuvette 10, the porous substance is placed. After that, the system of thermoregulation is set up, the necessary response temperature of the bridge is set to 5 resistances according to the indications of a wet 8 or a dry 9 thermoresistance. The pa of shelves II are laid to fabricate samples or selected samples of the machine 1 in their natural state. assembling the device: sealing the container 2, connecting the corresponding connectors of the thermoregulation system and power supply of the automatic elements. Thermal protectors 8 and 9 carry out a control check of the operation of the thermostat by indicator 6. Thereafter, an indifferent gas is supplied from the tank 13 through the pressure regulator 14 to maintain a high humidity of the vapor-air mixture. The assembled device is transported to a laboratory, where it is stored until testing of samples (coffin). The proposed device maintains the samples in their natural state in the case when the temperature in the sealed container is ambient. The invention The device for maintaining the natural state of the samples of rocks, including a heat insulating body with a sealed container, in which the samples are placed and the moisture control system containing the solution cuvette, in order to increase the duration of storage of samples in their natural CONDITION equipped with an indifferent gas cylinder, connected by a pressure regulator with a sealed container, made with a thermal control system, assembled from thermal resistances , heating coil and thermostat.
