MINING AND ENVIRONMENT IN LUGU IRON MINE

Lugu Iron Mine brought about a great development in industry. Some errores in the processes of construction and mining leaded to degeneration of environment and revival of debris flows due to lack a study on the relationship between mining and environment. Therefore,the Chengdu - Kunming Railway,Xide-Xichang Highway, Sichuan-Yunnan and mine highways broke off and the river bed of Sunshui River has risen to endanger the Lugu town.The mine and the department concerned pay great attention. The following measures for controlling debris flows have been taken: 1. abandon the plan for carrying the ore out at Xintiecun Station; 2. reform concentrated transport into carrying ore by vertical shaft and tunnel so as to lighten the slope destruction; 3. strengthen the railway bridge piers in Yanjing Gully so as to raise the capacity against debris flow damages;4. carry on comprehensive prevention of debris flows, weaken the hydrodynamic conditions of debris flow formations and decrease the loose debris materials so as to lessen the scales of debris flows and the frequences of debris flow occurrences, and recover the ecologic environment; 5. strengthen the flood prevention of Lugu Town and ensure its safety.
