Abstract

The invention belongs to the technical field of roadway support, and discloses an anchor net supporting method, which comprises the following steps of: tightly attaching a first net piece to one sideof a roadway according to the position of the roadway needing anchor net support, drilling a large arm by using mechanical equipment to prop against the central position of the net piece, starting todrill a hole, mounting a seam pipe anchor rod in the hole, and anchoring the net piece and a rock mass; arranging a second net piece according to the net piece lap joint spacing, and then anchoring the central position of the second net piece; overlapping and pressing the lapping area of the first net piece and the lapping area of the second net piece, and anchoring the corner area of the lappingarea on the rock mass through an anchor rod for net lapping; and repeating the steps, and finishing anchor net supporting construction from one side of the roadway to the top plate and from the top plate to the other side of the roadway. According to the method, an existing anchor net supporting technological method is simplified, and efficiency and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to an anchor net support method. Background technique [0002] With the continuous increase of domestic open-pit to underground mining, the anchor-mesh support of underground excavation roadways has been widely used. In the existing technology, large-scale mechanized anchor net support has gradually replaced manual construction, aiming to reduce labor intensity and improve operational efficiency. [0003] However, in actual construction, in order to ensure the quality of anchor bolt construction, the construction preparation operation is more complicated. It is necessary to manually measure the roadway, mark the anchor bolt position, and find points for drilling construction according to the standard. The advantages of mechanized operation cannot be brought into play. The efficiency of the equipment cannot be exerted. In addition, there are still problems such as the misma...
