Strengthening and correcting scheme of highvoltage power line tower in minedout area of fully mechanized topcoal caving face of coal mine

Abstract

Abstract: Abstract:The safe operation of the highvoltage power transmission line above minedout area of the coal mine fullymechanized topcoal caving face is threatened and damaged by the mining. The influence of the ground deformation of the minedout area on the power transmission steel tower was studied in detail. Based on this, referring to domestic and overseas treatment scheme of highvoltage power line tower strengthening in minedout area, a strengthening and correcting scheme of highvoltage power line tower on the minedout area of fully mechanized topcoal caving face was proposed. The scheme had been implemented, and better result was obtained.

Key words: Keywords:coal mine, fullymechanized topcoal caving face, minedout area, highvoltage power line tower, protection, strengthening
