松藻矿务局金鸡岩选煤厂是一座1986年建成投产、设计年生产能力120万吨的动力煤选煤厂。厂远离繁华闹市、地处夹皮山沟,从山顶俯视,映入眼帘的是一派绿树葱茏的亮丽风景。选煤厂先后被市、县授予环境保护先进单位,并被重庆市人民政府命名为“园林式工厂”。 然而,在厂投产初期,由于矿井采煤机械化程度的提高,煤质发生变化,煤的泥化程度加重,细煤粒在洗水中不沉淀,煤泥水浓度高达500克/升,造成煤泥水管道堵塞。厂房内、厂区的公路上煤泥水四处漫延,
Songzao Mining Bureau Jinjiyan Coal Preparation Plant is a thermal coal preparation plant with a production capacity of 1.2 million tons designed and put into operation in 1986. The factory is far away from the bustling downtown, is located in the Jiapishangou, and overlooks the top of the mountain. It is a bright and beautiful landscape with green trees. The coal preparation plant was successively awarded the advanced unit of environmental protection by the city and county, and was named “garden factory” by the Chongqing Municipal People’s Government. However, at the initial stage of plant operation, due to the increase in the degree of mechanization of coal mining, coal quality changes, the degree of coal argillization increases, fine coal particles do not precipitate in wash water, and the concentration of coal slurry is as high as 500 g/l, resulting in slime water pipelines. Blocked. Slurry water spreads over the roads in the plant and the plant area.
