摘要
随着矿井开采深度加大,煤仓的高度增高,已无法采用普通反井法施工煤仓。本文结合工程实例,介绍了LM—120型反井钻机施工煤仓的施工工艺,实践证明,该工艺不仅能够降低工人的劳动强度、提高施工工效和经济效益,更重要的是能提高施工安全生产系数。
As the mining depth increases, and the height of the coal banker also increases. As a result, the normal back-well drilling method can not be used for the construction of coal bunker. Based on the engineering example, this paper introduces the use of bunker construction technology, of LM - 120 type back-well drilling. Practice has proved that this technology can not only reduce the labor intensity, improve construction effciency and economic benefts, but can also improve the construction production safety coeffcient.
