Abstract: Изобретение относится к горной промышленности и может быть использовано при проходке выработок в соляном горном массиве, свойства которого связаны со слоистостью структуры горных пород. Техническим результатом изобретения является ускорение разрушения горной массы при отбойке породы от забоя соляного горного массива, имеющего слоистую структуру. Достигается это путем направления скалывающих ударов вдоль слоистой структуры соляного массива. Для этого исполнительный орган машины снабжают необходимым количеством скалывающих инструментов, направленных вдоль слоистой структуры соляного горного массива, жестко закрепляют скалывающие инструменты параллельно слоям и изменяют направление удара одновременно всех скалывающих инструментов поворотом машины, придают возвратно-поступательное движение скалывающим инструментам так, что скалывающие удары наносят в направлении соляного массива вдоль слоистой структуры. Благодаря разрушению соляного массива по направлению слоистой структуры происходит скалывание вышележащих кусков, причем скалывание происходит так, что минимально разрушаются продольные слои, вследствие чего откалываются более крупные куски соляного массива и не происходит переизмельчение руды. Таким образом добиваются увеличения крупности кусков и снижения объемов мелкой фракции руды и пыли в отбиваемой горной массе при разрушении соляного горного массива. 1 ил.
