Description

Technical field [0001] The invention relates to the technical field of open pit blasting, in particular to a control system and operation method for the boundary loss and dilution of an open blast ore body. Background technique [0002] In the design of open pit mine blasting, the method of piercing and blasting is usually adopted at the boundary between ore and rock. When blasting holes are arranged on one side of the ore body, it is necessary to determine the position of the blasting line after blasting, and then determine the last row of blasting holes according to the backlash distance Therefore, the setting of the line position after blasting is directly related to the loss rate and dilution rate of the blasting design, which affects the economic benefits of the mine. In open blasting, based on the line position after blasting and the principle of the blasting funnel, the blasting buffer surface produced is an inclined plane with a certain inclination. Combined with the spat...
