A fine-tuning method of hole layout to improve blasting effect based on rtk blast hole positioning technology

Abstract

The invention discloses a hole arrangement fine adjustment method based on the RTK blast hole positioning technology and used for improving the blasting effect. The hole arrangement fine adjustment method comprises the following steps that a surface soil layer of a mining area is cleaned, and a rock exposing layer operation face is smoothened; design, construction and blasting ate carried out according to the rock exposing layer operation face; blast heap extracting and loading operation is carried out to form a first rock stratum ladder operation platform; preset hole arrangement is carried out on the first rock stratum ladder operation platform, a preset hole arrangement blasting area of a blast hole ultra-deep blasting crater is marked into a hole arrangement forbidding scope on the first rock stratum ladder operation platform by means of the RTK blast hole positioning technology; the preset blast hole position of the first rock stratum ladder operation platform is adjusted; drilling and blasting operation is carried out according to adjusted blast holes; blast heap extracting and loading operation is carried out to form a second rock stratum ladder operation platform; and above operation is repeatedly executed. The blasting effect of explosive to rock masses is strengthened, the energy using rate is improved, the blasting quality is improved, and the blasting cost is reduced accordingly; the upper-layer blast hole ultra-deep position duplication hole arrangement is avoided, and the blasting operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of blasting in open-pit mines, in particular to a method for fine-tuning hole layout for improving blasting effects based on RTK blast hole positioning technology. Background technique [0002] The mining industry is the foundation of modern industry and plays an important role in the national economy. The role played by the mining industry on social development is obvious. With the rise of many new industries in recent years, it has declined, but it is still an important pillar of the national economy. Both historians and anthropologists attach great importance to the important role of mineral products in human progress and social and economic development, pointing out that "human progress is measured by the ability to use minerals, and modern humans are almost completely dependent on the mineral kingdom for survival." [0003] With the rapid development of the economy, the consumption of mineral resources...

Problems solved by technology

As a result, a series of "blasting funnels" appeared on the surface of the rock mass at the lower steps. In the next stage of perforation construction, it was difficult to penetrate through the "blasting funnels", and drill stuck and collapsed holes often occurred, resulting in low porosity

Once the blasting is carried out, due to the loose rock mass in the upper filling section, the explosive energy leaks out prematurely, and the surface of the blasting pile is large, resulting in poor blasting effect and easy to cause flying rocks, leading to accidents
