(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ОТНОСИТЕЛЬНЫХ СМЕШЕНИЙ ГОРНЫХ ПОРОД(54) DEVICE FOR MEASURING RELATIVE MIXTURES OF MOUNTAIN BREEDS
Изобретение относитс к измерени м и испытани м и может быть использовано при определении относительных смещений боковых пород при разработке подземным способом угольных и других пластовых месторождений полезных ископаемых. Известна установка реостатного типа дл дистанционного измерени относительных смещений горных пород, разработанна ВНИМИ 1. Установка предназначена дл наблюдени за поведением кровли в подземных выработках путем измерени смещени ее относительно почвы. В комплект установки вход т измерительна станци типа СРД-2, датчики реостатного типа РД-1 или РД-2 и штепсельна коробка ПП-2. В реостатных датчиках перемещение горных пород преобразуетс в изменение электрического сопротивлени , которое определ етс измерительной станцией . При этом плавное изменение величины деремещени соответствует ступенчатому изменению сопротивлени . Недостаток этой установки - больша чувствительность контактов датчика к окислению , чувствительность гальванометра к ударам, сотр сени м, влажности, необходимость проведени подготовительных работ в месте установки устройства. Известно устройство дл измерени относительных смещений горных пород, включающее измеритель давлени , гибкий рукав и датчик, выполненный в виде м гкой оболочки и заполненный рабочей средой 2. Недостатком этого устройства вл етс то, что м гка раст жима оболочка может прин ть любую форму при посто нном объеме , поэтому в случае смещени пород при неизменном объеме, что может быть в случае конвергенции, устройство не будет фиксировать это смещение. Цель изобретени - расширение ббласти использовани устройства путем обеспечени измерени сближений почвы и кровли пласта в очистных забо х. Поставленна цель достигаетс тем, что оболочка датчика выполнена из нераст жимого материала. На чертеже схематически показана установка устройства в очистном забое крутого пласта. Устройство дл измерени относительного смещени горных пород состоит из датThe invention relates to measurements and tests and can be used in determining the relative displacements of lateral rocks in the development of coal and other stratum mineral deposits by the underground method. The known installation of a rheostat type for remote measurement of relative displacements of rocks, developed by the All-Russian Research Institute of Applied Geometry 1. The installation is intended to monitor the behavior of the roof in underground workings by measuring its displacement relative to the soil. The installation kit includes a measuring station of the type SRD-2, rheostatic sensors of the type RD-1 or RD-2 and a PP-2 plug-in box. In rheostatic sensors, the movement of rocks is converted into a change in electrical resistance, which is determined by the measuring station. In this case, a smooth change in the magnitude of displacement corresponds to a stepwise change in resistance. The disadvantage of this setup is the high sensitivity of the sensor contacts to oxidation, the sensitivity of the galvanometer to shock, stress, humidity, the need for preparatory work at the installation site of the device. A device for measuring relative displacements of rocks is known, which includes a pressure gauge, a flexible hose and a sensor made in the form of a soft shell and filled with the working medium 2. A disadvantage of this device is that the soft stretch shell can take any shape volume, so in the case of displacement of rocks at a constant volume, which may be the case of convergence, the device will not fix this displacement. The purpose of the invention is to expand the field of use of the device by providing a measurement of the approach of the soil and the roof of the formation in the clearing holes. The goal is achieved by the fact that the sensor envelope is made of an inextensible material. The drawing schematically shows the installation of the device in the stope of a steep seam. A device for measuring the relative displacement of rocks consists of dates
