Abstract
Currently, the demand for stone construction materials in Lao PDR to serve industrial and traffic works is very large. Currently, the management of mining activities at limestone quarries in Lao PDR is facing many difficulties due to the existence of many types of mines, mining technologies, and equipment. The occupational safety and environmental protection used at the limestone quarries have not been paid due attention. The loss and waste of natural resources are increasing. In particular, labor accidents caused by unsafe drilling and blasting activities often occur at the limestone quarries of construction materials in all provinces of this country. The article analysed the current situation of drilling and blasting activities at the limestone quarries of construction materials of Lao PDR, thereby proposed a method to assess risks and unsafety in drilling and blasting activities at the limestone quarries for mining the construction materials to improve the efficiency of the mining management and safety in Lao PDR.
