Guangdong Bulletin Zijin Mining Dam failure

December 21 Morning, the Guangdong Provincial Inspection Commission held a press conference, informed the "9.21" Xinyi Purple Gold Mining Co., Ltd. (hereinafter referred to as "Xinyi Zijin") Silver ore mine Gao Qi Ridge tailings dam break, resulting in significant casualties and property losses of investigation and treatment.　　A total of 36 persons responsible were involved, 15 of whom were transferred to the judiciary, including 4 agency staff and 11 business personnel. Guangdong Province Inspection Commission in the circular also pointed out that the local government has been instructed to Xinyi Zijin company to claim, to effectively safeguard the legitimate rights and interests of the masses. According to the Government of Xinyi 21st, the day Xinyi court to accept the "9.21" Xinyi Zijin Mining tailings dam accident caused the death of the personnel of the personal injury compensation cases, involving 22 people, the claimed amount of money has reached more than 11 million yuan.　　According to the Zijin mining October 17 announcement, the Xinyi government has sued Zijin Mining wholly owned subsidiary Xinyi Zijin and Treasure Source mining, claims 19.5 million yuan. The three major causes of the tailings dam break September 21, by the typhoon "Van Asia" brought by the rare heavy rain impact, Maoming Xinyi Purple Gold Mining Co., Ltd. Gao Qi Ridge tailings dam event occurred, resulting in significant casualties and property losses. A total of 22 people were killed, according to Maoming, Xinyi housing appraisal approved by the Housing Authority, the House 523 households, 815 households were damaged.　　Affected by the dam break, the downstream catchment areas such as transportation, water conservancy and other public infrastructure, as well as farmland, crops and other serious damage. According to the investigation report adopted by the Standing Committee of December 14, the "9.21" Gao Qi Ridge tailings dam-breaking incident is caused by the extraordinary natural disaster and related units of the illegal violation of the safety of the cause of the accident, exposing the relevant enterprises illegal construction production, safety production responsibility system is not implemented,　　The relevant government and functional departments are not in place, and a small number of leading cadres violate the law and other issues.　　The report said that the cause of the tailings dam break mainly in the following three aspects.　　The cause of the dam break is that the torrential rainfall caused by the typhoon "van-Asia" is more than 200 years. The direct cause of dam break is: the tailings reservoir drainage well in the construction process was arbitrarily elevated inlet elevation, the enterprise to the tailings reservoir operation Management security responsibility is not implemented. After investigation, the lowest inlet of No. 1th drainage well in the tailings reservoir was modified to raise 2.597 meters without authorization, which seriously affected the discharge capacity of the drainage wells. At the same time, Xinyi Zijin to the tailings reservoir operation Management security responsibility is not implemented.　　In the flood season before the arrival of the No. 1th drainage wells, the lower six water holes are basically blocked by the arch, resulting in excess storage and reduce flood discharge capacity. The indirect cause of dam break is that the standard hydrologic parameters and catchment area of tailings reservoir design are unreasonable, which leads to low actual flood control standard. First, the original design in 200 years, the standard rainfall is unreasonable, 44.5 mm deviation. Secondly, there is a large error in the design of catchment area of tailings reservoir. The total water area of Gao Qi Ridge tailings reservoir should be 3.743 square kilometers, the design value is 1.24 lower than the actual value.square kilometers, resulting in a larger discharge pressure than the original design.　　Third, the original design did not consider the establishment of emergency flood relief facilities. Illegal construction and management of the absence of the investigation, Xinyi Zijin Company illegal construction of tailings reservoir, unauthorized breach of the tailings reservoir major design changes, long-term illegal production, management confusion, safety measures are not in place, safety production responsibility system is not implemented, the main responsibility for the incident occurred. It mentioned that the company has not approved the production of illegal products without the Environmental Protection Department. October 2009, Guangdong Province Environmental Protection Department of the Silver-rock tin mine project in the trial production acceptance, because the project concentrator crushing system has not been required to install pulse bag dust removal device, clear dispatch does not agree with Xinyi Zijin company put into trial production. Xinyi Zijin Company after rectification, in July 2010, the Provincial Environmental Protection Office issued a consent to the company trial production for 3 months.　　But before this, without the acceptance of the Environmental Protection Department, Xinyi Zijin Company has been illegal production. The communication also mentions that the relevant government and functional departments are responsible for the occurrence of incidents. Guangdong Provincial Security Supervision Bureau of the relevant departments of the completion of the examination and acceptance of the work is not in place, provincial, municipal and county levels of production safety supervision departments of Xinyi Zijin company did not obtain a safe production of tailings warehouse license will be illegal production, illegal discharge tailings sand and other acts of supervision, crackdown. The former Guangdong Provincial Economic and Trade Commission (now the Committee) concerned departments did not approve the project according to the prescribed procedures, did not seek public opinion, the project follow-up supervision is not in place. Xinyi Land and Resources Bureau of illegal land, supervision ineffective, conceal Xinyi Zijin company illegal land. Provincial, municipal and county level of environmental protection departments of the day-to-day supervision of the staff is not in place. The local government failed to detect and stop Xinyi Zijin Company's illegal production and construction activities in time. Xinyi government is not in place, supervision is weak.
