Guizhou Open Group is a set of phosphorus in phosphate rock mining and processing of phosphorus into a large state-owned enterprise. Affected by financial crisis, the phosphate group was reduced up to 40%. Faced with the grim situation inside and outside, as a pillar of phosphorus chemical industry enterprises in Guizhou open phosphorus groups on how to deal with?屈庆CHU, Guizhou Group Chairman opened phosphorus, as a leader in open phosphorus, phosphorus屈庆CHU proposed opening the road to deal with the crisis is the "two truss, between stronger." Lin said屈庆truss pocket import, is how to improve the rate of resource exploitation. Phosphate groups at the beginning by Shaba mines, through the 3000 meters of the underground roadway, came to the extractive noodle. In 2008, the phosphate groups at the international level the first time adopted the "filling mining method", which put phosphogypsum backfill mined-out area of mining technology was received first prize for scientific and technological progress the national chemical industry. This filling method in accordance with the mining, ore mining, how often, on the number of backfill into the phosphogypsum. Previously reserved for the support pillar not only by permutation; whole goaf all filled up, the mining population has also been firmly locked. The truss屈庆pocket-lin said the export of phosphorus chemical industry is how to deal with the problem of phosphogypsum waste residue. Phosphogypsum are all the phosphorus chemical industry fatal pain, the phosphorus Phosphogypsum year alone generated over 200 million tons, in the past, a great open-air piling up environmental problems. After 3 years research, the phosphorus developed with independent intellectual property rights Phosphogypsum brick technology, to capture the world-class engineering problems, but also to remove the constraints of phosphorus chemical obstacle to development.

Guizhou opens the phosphorus group is a fair rock phosphate mining and the phosphorus intensive processing is a body's large-scale State-owned business .Is affected the financial crisis, Opened the phosphorus group once to reduce production reaches 40%. Facing stern inside and outside situations, Opens the phosphorus group how as Guizhou phosphorus chemical industry prop enterprise to deal? Qu Qinglin, Guizhou opens phosphorus group chairman, the achievement opens the phosphorus to command troops the human, Qu Qinglin proposed the phosphorus deals with road of the crisis is “grips tight two, to do strongly among”. Qu Qinglin said grips the tight pocket's import, how is to raise the resources recovery ratio the question. Is opening the phosphorus group with Sha Bakuang, passes through 3000 meter mine shaft tunnels, arrived at the excavation surface. in 2008, opened the phosphorus group internationally for the first time to use “the backfill mining method”, this kind obtained in the past the phosphorus gypsum waste residue backfill worked-out section's mining technology the national chemical industry advance in technology first prize. According to this kind of backfill law mining, picks the how much ore, to enter the how much phosphorus gypsum on the backfill. Not only formerly remained makes support's ore column to replace; After the entire worked-out section fills up completely, the mining mouth firmly is also locked. But Qu Qinglin said grips the tight pocket's export, is how to process the phosphorus chemical industry waste residue phosphorus gypsum the question. The phosphorus gypsum waste residue is all phosphorization ICBC industry fatal pain, opens the phosphorus gypsum which the phosphorus produces every year to have more than 200 ten thousand tons, formerly the air storage created the very big environment hidden danger. After 3 year attack, opened the phosphorus to develop had the proprietary intellectual property rights phosphorus gypsum make bricks technology, has solved this world-class project difficult problem, also eliminated the restriction phosphorus chemical industry development barrier.本回答被提问者采纳
