Method of blasting strong complex-structure rocks in mines


Download the page from the catalog (2022) 


Purpose

Extraction of minerals in a massif of strong and ultra-strong stressed rocks of complex structure at uranium and iron ore mines


Characteristics
The essence of the method lies in identifying in thin sections, made from oriented rock samples, the main systems of microcracks, their spatial position, by which the intensity and direction of the predominant forces of rock pressure can be determined. In these zones, drilling of cut holes is performed, where charges of variable cross-section cumulative action are formed, and in the hanging and footwall sides — drilling of breakage holes, where charges of solid construction with pot-shaped expansion at the ends in the zone of tensile stress are formed, blasting with delay from cut charges in the zone of predominant forces of rock pressure, and breakage charges — in a checkerboard pattern in the zone of tensile stress


Advantages
Improving the performance of explosive charges in fan-shaped holes ensures the destruction of the ore deposit in the block with uniform crushing of strong rocks and reduction of specific explosive material consumption, increasing the efficiency of the explosion, productivity of crushing and sorting complexes, and transport vehicles

Technology for performing preparatory workings in a massif of strong stressed rock by explosive energy


Download the page from the catalog (2022) 


Purpose

Formation of a slot cavity in strong stressed rocks using explosive energy


Characteristics
The technology is based on new methods of forming a slot cavity by introducing additional free cavities — enlarged diameter boreholes and borehole charge structures — into the slot design. The formation of the slot cavity is ensured by detonating charges in a three-tier cylindrical or prismatic stepping slot with delay, starting with cumulative effect charges of the 3rd tier and ending with charges of the 1st and 2nd tiers on the compensation borehole


Advantages
Due to the redistribution of static stresses as the excavation progresses, the depth and volume of the slot cavity increase, as well as the drilling speed and rock fragmentation quality, while the specific consumption of explosives and blasting means decreases
