Zhejiang Weiguo Mining Co., Ltd. is a large-scale mining enterprise with a total investment of 400 million yuan in Changchun Village, Wukang Town. In 2009, Weiguo Mining took the lead in the whole process of the whole process of crushing and processing in the whole city. The processing units and materials warehouses with a length of several hundred meters were all closed, and the spray facilities at each material discharge port were installed with sprinklers. At the same time, the company has invested more than 4 million yuan to build a whole sewage recycling system, so that there is no mine dust cover on the street trees in the mining area. This year, the reporter entered this mining enterprise and found a new discovery: it not only built three tall, fully enclosed greenhouses, but also installed all the machines inside, and installed three sets of vacuum cleaner systems to completely eliminate the dust in the mine processing. Take a leak. Shareholders Weiguo, said in June last year put into the construction of three iron skin closed greenhouses, covering a total area of 14,000 square meters, maximum height of 17.8 meters, the equivalent of six stories high building, the largest span reaching 50 meters Three metal sheds were built along the mountain, and the entire mining enterprise was mechanically wrapped inside. Walking into the central intelligent control room in the middle of the iron shed, more than 30 computer screens show the production status of the workshop. Through the sealed glass window, we can see that the conveyor belt continuously sends the broken stone to the third iron shed. There is a stone warehouse. The transportation vehicle is loaded with stone and transported to the dock. There is no warehouse along the way. The sprinkler water and dust removal is a confined space. There is no chance for the dust to be probed at all. After arriving at the dock, the stone warehouse will be transported by the conveyor belt and the hundreds of tons of iron shell transport ship parked on the side of the ship. There are two other moments when the stone is disembarked. The high-pressure water column is directed at the stone. "In this rainy day, there is no need to spray water, but we still insist on ensuring that the whole process is sealed and dust-free." Another shareholder Wang Zhongqiang introduced. He Weiguo also introduced to reporters another important reason why there is no dust leaking out of the workshop. That is, last year he spent more than 1.8 million yuan to install three sets of pulse dust removal systems, the most fluttering in the “one broken workshop†and eight vibrating screen dusts. The three large-scale industrial vacuum cleaners that consume hundreds of kilowatts of power will absorb a large amount of dust in the workshop into the machine cavity, thus maximizing the dust. This is an important reason for the lack of dust coverage on the leaves and leaves of workshops and transportation lines and street trees throughout the plant. Not only that, the dust removal of Weiguo Mining has also expanded to the blasting and mining stages. Wang Zhongqiang drove the reporter to the top of the mining area where the quarry was being stoned. He pointed to the layer of soil slope on the hillside and said: "The former mining was a barbaric extreme mining. The middle blasting mountain collapsed. Now it can't be like this, but the step is Maintenance-type mining means mining by side, greening on the side, and mining down one layer. Each floor is separated by 15 meters, leaving a soil slope about 6 meters wide. Is the yellow mud not transported from the mountain? This is the preparation for greening. "This is not. There are several loading and unloading trucks under the mountain that are loaded with yellow mud and transported to the mountains. They are filled on the already-exploited stone slopes to prepare grass. In addition, he also said that even in the blasting of boreholes, the use of vacuuming devices to minimize dust.

Walking into the workshop of this mining company, you will not feel that this is a stone processing enterprise. It is more like a modern high-tech enterprise, producing sterile-grade sealing products.
