Abstract

The invention discloses a one-time well completion blasting method of a measure well. The method comprises following steps: firstly, trolley drilling, wherein a center hole and four empty holes are sequentially drilled in a lower chamber of the measure well upwards, four rings of charging holes are drilled from inside to outside, the center hole is located in the center position of the measure well, the empty holes are formed in the periphery of the center hole and are arranged in a square manner, the four empty holes are formed in the four top points of the square, the four rings of charging holes are sequentially provided with four, eight, nine, and fourteen charging holes from inside to outside, and each ring of charging holes are arranged on the circumference with the center hole as the round center at equal distances; secondly, charging, wherein emulsion explosives and detonators are loaded in the center hole and all the charging holes, and after charging, stemming is used for plugging hole openings; thirdly, blasting, wherein blasting is carried outside electronic detonator holes, and blasthole millisecond blasting is carried out. According to the one-time well completion blasting method of the measure well, the construction efficiency of the measure well is effectively improved, and the one-time well completion blasting effect and the wall face smoothness of the measure well are improved.

Description

technical field [0001] The invention belongs to the technical field of mine mining, and in particular relates to a one-time well-forming blasting method for a measure well. Background technique [0002] In terms of metal mine raise tunneling technology, the upward segmental blasting method has been used for a long time. Due to the complexity of blasting procedures, the safety of related personnel and equipment, and the constraints of rock drilling machinery and equipment, it has always been highly regarded by people. Follow and explore. [0003] In recent years, due to the popularization and use of high-efficiency rock drilling rig machinery and equipment in mining enterprises, as well as the advantages of good safety and high efficiency of blasting a well into a well, it can improve the working environment and equipment safety of relevant personnel during the excavation of the measure well; therefore , more and more research institutions and enterprises have invested a lot...
