皖北矿区煤矿煤巷锚网支护体系的建立与发展

Establishment and Development of Bolt Net Support System of Coal Mine Roadway in Mining Area of Northern Anhui

近几年,在我国煤矿支护中,煤巷锚网支护取得了大面积推广应用,该技术比传统的架棚支护有着很多优点,节约了大量的人财物,减轻了职工的劳动强度,大大提高了劳动生产率。煤巷锚网支护体系在皖北矿区已全面推广,煤巷锚网支护率已达到90%以上。着重介绍锚网支护体系在皖北矿区的发展历程及顶板控制的成功经验。

In recent years, coal roadway bolt net support is applied in large scale in China~ coal mines support. The technology has many advantages than traditional shed shoring, which saves a lot of human, financial, reduces the labor intensity of workers, greatly improves the labor productivity. Bolt net support system of coal mine roadway has been generally promoted in the mining area of North- ern China, and the support rate of coal roadway is up to 90%. This paper focuses on the successful experience of roof control and the development course of bolt net system in mining area of Northern Anhui.
