Abstract

The invention discloses a processing method for exploiting marble with a static cracking agent and belongs to the technical field of stone processing. The static cracking agent is prepared from, by weight, 40-50 parts of over burnt lime, 7-10 parts of anhydrite, 5-8 parts of calcined alum, Beta-naphthyl sulfonate formaldehyde condensate, 6-9 parts of sodium gluconate, 7-8 parts of sodium sulfate, 5-10 parts of sodium bentonite, 1-3 parts of expanded graphite, 1-4 parts of sodium borate, 2-3 parts of activated sludge, 1-2 parts of quartz powder, 2-3 parts of ligneous calcium sulphonate and 1 parts of phenol. When the marble is exploited, the static cracking agent has the advantages of being short in blasting time and high in safety coefficient and blasting efficiency. Soaking the marble in water helps facilitate drilling and successfully conduct smashing. When the marble is smashed, a high temperature and a reasonable ratio of water to lime can best promote swelling of the static cracking agent, so as to finish blasting of the marble.

Description

technical field [0001] The invention belongs to the technical field of stone processing, and in particular relates to a processing method for mining marble with a static breaking agent. Background technique [0002] Marble is a commonly used stone for architectural decoration. Because it has mixed colors and forms distinctive patterns, it is often used as a decorative material. With the development of the modern construction industry, people's demand for marble is increasing. At present, people mainly use manual mining and blasting mining for marble mining, but these two methods have the disadvantages of safety hazards and time-consuming and labor-intensive shortcomings. Therefore, using a static breaking agent to mine marble can eliminate the safety hazards of blasting mining and the time-consuming and labor-intensive defects of manual mining. [0003] Static blasting is a blasting method that uses a static breaking agent to slowly load the crushed object until it cracks a...
