Description
Характеристики прочности материала на одноосное сжатие и сдвиг вл ютс важными показател ми, необходимыми дл аналитического решени вопросов механики горных пород.The material strength characteristics for uniaxial compression and shear are important indicators necessary for analytically resolving issues of rock mechanics.
Предметом изобретени вл етс способ получени механических характеристик хрупких материалов и, в частности, горных нород и угл при сжатии и сдвиге.The subject of the invention is a method for obtaining the mechanical characteristics of brittle materials and, in particular, mountainous gases and carbon in compression and shear.
Известные способы механического испытани горных пород и углей требуют изготовлени образцов определенной формы путем предварительной .механической обработки.The known methods of mechanical testing of rocks and coal require the manufacture of samples of a certain shape by preliminary mechanical processing.
Достоинством предлагаемого способа вл етс возможность использовани дл механических испытаний образцов произвольной формы.The advantage of the proposed method is the possibility of using arbitrary shapes for mechanical testing of samples.
Сущность предлагаемого способа механического испытани заключаетс в том, что берут образец испытуемого материала произвольной формы, заливают его цементом, оставл в заливке зазор, расположенный по плоскости, заранее определ ющей место разрушени образца , и путем изменени угла наклона указанного зазора к направлению приложени нагрузки задают образцу различные напр женные состо ни .The essence of the proposed method of mechanical testing is that a sample of an arbitrary shape material is sampled, filled with cement, leaving a gap in the fill positioned along a plane predetermining the place of sample destruction, and by changing the angle of inclination of the specified gap to the direction of load application, set the sample various stress conditions.
На чертеже показано в двух проекци х приспособление дл осуществлени способа. Оно выполнено в виде форм 1 и 2, между которыми расположен образец 3 произвольной формы, залитый цементом 4. Посредством прокладки 5 определенной толщины выполн етс зазор, которому придаетс тот или иной угол наклона к горизонтальной плоскости . Прокладка не дает возможности цементу св зать относительно друг друга движение форм, которые соприкасаютс только через испытуемый образец.The drawing shows in two projections a device for carrying out the method. It is made in the form of forms 1 and 2, between which an arbitrary shape of sample 3 is placed, which is poured with cement 4. Through the strip 5 of a certain thickness, a gap is made, which gives a particular angle of inclination to the horizontal plane. The gasket does not allow the cement to bind relative to each other the movement of the molds that are in contact only through the test sample.
При наложении на формы нагрузки , показанной на чертеже стрелками- , цементна заливка будет выдел ть из испытуемого образца элементарный объем, по толщине равный прокладке, вл ющейс предопределенным местом разрушени образца.When superimposed on the forms of the load, shown in the drawing by the arrows, the cement pouring will release from the test sample an elementary volume, the thickness equal to the gasket, which is the predetermined place of destruction of the sample.

личающийс тем, что, с целью использовани дл испытани образцов произвольной формы, его заливают цементом, оставл в заливке зазор, расположенный по плоскости, заранее определ ющей место разрушени образца, и путем изменени угла наклона указанного зазора к направлению приложени нагрузки задают образцу различные напр женные состо ни .In order to use samples of arbitrary shape for testing, it is poured with cement, leaving a gap in the pouring located along a plane predetermined in advance of the sample destruction, and by changing the angle of inclination of the specified gap to the direction of application of the load, different stress condition
