Abstract:

An Giang is one of the provinces in the Mekong Delta. The Seven Mountains rise in the midst of vast land with an area of 43,000 ha. This is the source of abundant construction materials for the province, exploration reserves reached 80,810,587 m3. In the past few years, the exploitation and processing of stone for building materials has been strongly developed, the industry and construction has increased from 11.12% in 2010 to 12.61% in 2015. This is the advantage of the province and meets the increasing demand of building materials market. Currently, in the province, five enterprises are licensed to exploit the rock and only concentrate in the areas of Mount Ba Doi, Mount Co To and Mount Giai with a total reserve of 76,494,087 m3, with the mining life from 10 to 30 years. However, the quarries are exploited by the open pit mining system by steep grade, cutting layer by blasting technology. The process of quarrying causes heavy pollution to the environment, disrupting the ecological balance, affecting the health and safety of workers, wasting resources... More advanced dust solutions, building water reservoirs after mining and modernization of mining and processing should be applied to improve management efficiency of stone exploitation in An Giang
