When using the Non-explosive rock cracking agents for blasting, make sure that the local temperature, the temperature of the silent breaker, the temperature of the mixed water, the temperature of the rock and the temperature of the container meet the requirements; check whether the drug packaging is damaged. Before proceeding, please make sure to prepare the following materials: pharmacy, clean mixing water, bucket, mixing bowl and scoop, bucket strip (horizontal filling), safety glasses, rubber gloves, spare clean water and towel.
In the crushing process, if the temperature is uncertain and the range is uncertain, its expansion pressure will also have a great influence, which also causes the grouting to have a great influence on the crushing effect. The efficiency and effect of crushing need to determine its temperature to avoid errors and affect the crushing effect.
The advantages of Non-explosive rock cracking agents are still relatively large, and in order to make better use of crushing agents, the relationship between crushing pressure and temperature is also known.
Design the crushing plan: first determine that there is at least one free surface (access surface) in front of the cloth, and the drilling direction should be as parallel to the free surface as possible; when cutting rock or concrete, the same row of drilling holes should be kept on the same plane as much as possible superior. The more free surfaces, the greater the amount of broken rocks per unit, and the higher the economic benefits. After the crushing plan is determined, first use a drilling rig to drill holes. The hole diameter, hole distance, hole depth and crushing design should be determined according to the specific conditions of the crushed object. Such as: concrete structure: presence or absence of steel bars, steel bar diameter, arrangement; rock structure: behavior, joints, size of broken objects, equal hole spacing and row spacing (resistance line distance) arrangement: hole spacing and row spacing size and rock Hardness, concrete strength and reinforcement are directly related. The greater the hardness, the higher the strength of concrete, and the thicker the reinforcement is, the smaller the hole spacing and row spacing, and vice versa. The hole spacing and row spacing are arranged.
