Analysis on Dust Production Mechanism and Control Measures in Drilling and Blasting Method Construction
Abstract
Drilling and blasting method of highway tunnel construction is the most serious damaging area of dust. The original dust concentration during operation of each procedure exceeded the national health standard number, which was a serious threat to workers’ health and safety. Dust generation mechanism of drilling, blasting, transportation and sprayed concrete on drilling and blasting was obtained, through to each the process of drilling and blasting method construction analysis. The control dust measures are analyzed and summarized, and the result has important theoretical significance to dust control of tunnel construction.
