Application of Anchor Sub-support Technology in Coal Mine Roadway
In the current coal mining,roadway excavation and support have the characteristics of close integration and interconnection,which has a certain impact on the overall roadway excavation efficiency,and is prone to the problem of mining and excavation succession tension in the actual coal mine production operation.Combined with the previous application of digging efficiency improvement measures,in the actual implementation of the more vulnerable to the influence of various factors,the need for mining enterprises to understand the value of anchor sub-support technology,in the application of technology to improve the effect of digging and support.To this end,first an overview of mining engineering,and then specifically analyse the principles and implementation points of the anchor rod sub-support technology,and then finally the field test,in order to expect to reduce the interference of the excavation and support operations,to improve the speed of roadway excavation.
