我省县以上地方煤矿,65％以上采用斜井开拓方式,其中除焦窑、磨窝和井陉县等少数煤矿外,均未安设防跑车装置,因而难免发生跑车事故,在这方面的教训是沉痛的。为此,本文介绍几种适于地方煤矿推广采用的斜井防跑车装置,并对计算步骤做一简述,不妥之处,欢迎批评指正,以裨于事。 More than 65% of the local coal mines at or above the county level adopt the inclined shaft exploiting method. Except for a few coal mines, such as the coke kiln, the mill nest and Jingxing County, no anti-sports car device is installed, so it is inevitable that a sports car accident will occur. The lesson in this respect is Painful. To this end, this article describes several suitable for the promotion of local coal mine shaft anti-car device, and the calculation steps to make a brief, inappropriate, welcome to criticism and correction in order to benefit things.
