Nanjing Metro responded to the "subsidence" accident: Initially judged as diesel generator due to quicksand | Diesel generator price / 2012-11-29

Around 11 am this morning, a bus accident broke out in downtown Nanjing. A bus from the south to the north slowly fell into the ground. Fortunately, no one was injured. The site of the subsidence accident was close to the construction site of Nanjing Metro Line 3. Some citizens said that the subsidence accident was related to subway construction.
At 12 o'clock noon, the Nanjing Metro quickly responded to the official Weibo, saying that the cause of the accident was "preliminarily determined to be caused by quicksand." The full text of the Weibo is as follows: "At 11 am, local subsidence occurred near the basement pit of Metro Line 3 Daxinggong Station. Initially judged to be caused by quicksand, it is actively being backfilled, causing no casualties and not affecting the normal operation of Metro Line 2."
At 3:40 in the afternoon, the Nanjing Metro responded again, saying that the primary cause of the accident was the leakage of water at the joint between the wall and the line of the second line, where the stratum was medium dense fine sand and was located in the Qinhuai River. Ancient roads, poor geological conditions, causing soil erosion, causing ground subsidence.
After the incident, relevant leaders from Nanjing visited the site and directed their efforts to organize traffic in a timely manner to divert traffic. The first time the bus was picked up and the pit was backfilled. Due to strong disposal, the accident did not cause traffic jams and casualties.
The reporter learned that at present, Nanjing Metro has organized expert site surveys to further analyze the causes of the accident, and at the same time organized the force to fill in the foundation pit as soon as possible, and strive to resume road traffic at 8:00 tonight (November 29).

Gold Gravity Refining Equipment

The STL water-jacketed Gold Concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.

The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.
