| description | The invention provides an explosive-free rock breaking method, an explosive-free rock breaking, digging and laying method and explosive-free rock breaking equipment used in the explosive-free rock breaking method. The explosive-free rock breaking method comprises the following steps: step one, forming holes in a rock body which requires to be broken; and step two, arranging a splitter, inserting wedge blocks of the splitter in the holes in step one, and then applying acting force to the holes in the rock body to expand the holes by the wedge block group. According to the explosive-free rock breaking method, explosive-free rock breaking of the rock body is realized by the explosive-free rock breaking equipment, and various problems caused by explosion of initiating explosive devices can besolved. Explosive-free rock breaking operation is realized, mechanical operation of various processes can be realized, the connecting time of the various processes is remarkably shortened, and thus, the purposes of increasing |
