The "Black Gold" of the Ninth Bureau of Hydropower Wins New Orders, and Guizhou Sand Makes Another Breakthrough in the Province

Recently, the Ninth Bureau of Hydropower successfully won the bid for the 4th bid of pavement maintenance engineering material procurement project of Hunan Expressway Group Co., Ltd. in 2023. The "black gold" of the Ninth Bureau entered the Hunan market for the first time and expanded again in the market layout of "Qiansha Province". The acquisition of purchase orders for pavement gravel materials in

2023 has achieved a breakthrough in "black gold" and "Guizhou sand out of the province", and the goal of expanding the business territory, marking the first time that the basalt sand and gravel business of the Ninth Bureau of Hydropower has entered the Hunan market after opening up the markets of Sichuan, Chongqing and Anhui. It will continue to supply high-quality materials for highway construction and pavement maintenance in Hunan Province, and effectively help local infrastructure construction.

"Black gold" refers to basalt aggregate, which has many advantages, such as compact structure, high strength and stability, hard rock, strong compression resistance, low crushing value, strong corrosion resistance, wear resistance, less draught, poor conductivity, asphalt adhesion and so on. It has a wide range of uses and high economic value, and is an important cornerstone of infrastructure construction. Relying on the research and development of "GEPI (Green Environmental Protection and Energy-saving Intelligence) Key Technology for Preparing High-quality Sand and Stone" and the core technology of mining led by the Ninth Hydropower Bureau, the "black gold" quality of the Ninth Hydropower Bureau has exceeded the standard of road construction projects, and has received unanimous praise from the industry. At present, it is mainly used in the construction of high-speed railways, expressways, airports and other fields. The "black gold" production base of the Ninth

Hydropower Bureau is located in Qingzhen City, Guiyang City, Guizhou Province. The "black gold" production technology is skilled. It has been more than 10 years since the first basalt production line of Luohaichong Sandstone System was completed and put into operation. Since the beginning of the construction of the production line, the Ninth Bureau of Hydropower has been aiming at building a brand of high-quality basalt sand and stone. In order to continuously meet the market demand and continuously improve the production technology, it has successively completed such scientific and technological studies as "Technical Research on Improving the Productivity of 9-16 mm Basalt Products" and "Improving the Qualified Rate of Super Ballast Quality". The project has won the title of "provincial green mine" in Guizhou Province for many times, such as the national utility model patent certificate and the first-class achievement of QC project in Guizhou Province.
