荣获“全国工业污染防治十佳企业”称号的徐州矿务局庞庄煤矿走清洁生产之路,成功探索出一条开采、洗选、处理全过程控制工业污染的新途径。 煤矿采煤所产生的矸石等固体废弃物,严重危害周围环境。庞庄煤矿除对矸石等固体废弃物进行综合利用外,注重把好现场开采第一关,实行采、运质量跟踪。煤矿成立选运科、矿井、区队三级管理网络,签订目标责任状,专人负责考核兑现,有效地遏制矸石混入,确保煤质。采煤工区严格按标准开采,煤、矸石分别装运,皮带运输设立两道排矸系统,层层设防,把好了清洁生产的第一道关卡。 庞庄煤矿的洗选工段在两座洗煤厂上大做文章。依靠科技进步,推广应用全底流浮选新工艺等先进技术,生产出荣获国家银质奖的六、八级冶炼精煤和省部优产品。全底流浮选新工艺也获得江苏省科技进步金牛奖和国家实用新型专利。 洗选工段产生的矸石、洗煤水、煤泥怎样处理呢?庞庄煤矿大胆创新,把矸石加工制成发热量为
Won the “Top Ten Industrial Pollution Prevention Enterprise” title of Xuzhou Coal Mining Pangzhuang Coal Mine to clean production, successfully explored a mining, washing, handling the whole process of controlling industrial pollution a new way. Coal wastes generated by coal mining and other solid waste, seriously endangering the surrounding environment. Pangzhuang Coal Mine in addition to the comprehensive utilization of solid waste such as gangue, pay attention to good on-site mining first pass, the implementation of mining, transport quality tracking. The Coal Mine has set up a three-level management network of election transport sections, mines and district teams, signed a target responsibility form and a special person is responsible for checking and cashing in, effectively preventing waste rock from mixing and ensuring coal quality. Coal mining area in strict accordance with the standard mining, coal, gangue were shipped, the belt transport set up two gangue system, fortification layers, put the first clean production level. Pangzhuang coal washing section in the two coal washing plant big fuss. Rely on advances in science and technology, promote the use of all-inclusive flow flotation new technology and other advanced technologies to produce the national silver medal awarded six or eight smelting coal and the provincial Department of superior products. Full-flow flotation of new technology also won the Jiangsu Provincial Science and Technology Progress Award and the national utility model patent. Waste treatment section generated gangue, coal washing, slime how to deal with it? Pang Zhuang bold innovation coal mine, the gangue processing heat made of
