AI Technical Summary

Technical Problem

In existing technologies, when adding ore transfer conveyor belts during the infrastructure construction phase, blasting causes significant dynamic disturbance to adjacent existing facilities and surrounding rock, and the conveyor belts are prone to cracking and roof instability.

Method used

The existing facilities are fully enclosed by a composite protection structure. Excavation is carried out using mechanical rock breaking and drilling and multiple cycles of blasting. Combined with anchor mesh support and a step-by-step construction sequence, permanent lining is carried out after monitoring the displacement of the surrounding rock.

Benefits of technology

This effectively reduced the impact of blasting on existing facilities, decreased the risk of conveyor belt cracking and roof instability, and improved construction safety and quality.

Abstract

The application discloses a construction method for adding an ore transfer rubber belt way during capital construction, which comprises the following steps: adopting a composite protection structure to fully close and protect a through section of an existing rubber belt way, fixing existing cables and optical fibers in the rubber belt way, adopting a mechanical crushing and rock drilling method to excavate a section near a mine portal, and performing anchor net support, adopting a multiple cycle blasting method to excavate a normal section of the rubber belt way, excavating an upper part of a transfer station chamber, and performing anchor net support, excavating a lower part of the transfer station chamber, and performing anchor net support, monitoring the displacement of surrounding rocks of the section near the mine portal, the normal section of the rubber belt way and the transfer station chamber, waiting for the deformation of the surrounding rocks to be stable, performing permanent lining on a straight wall section, performing permanent lining on an arch section, finally performing permanent lining on a bottom plate section, and installing rubber belt way equipment, so that the influence of blasting on existing facilities is reduced to the minimum, the peak value of blasting vibration is effectively reduced, and the disturbance of one-time full-face blasting on adjacent facilities is solved.
