It was used as a patented product by Ingersoll Rand for mining support. In the early 1980s, the Beijing Institute of Well Construction conducted exploratory tests on slotted pipe anchors in the laboratory and achieved good results. Later, it was gradually promoted and applied in the coal system.


Split set bolt is a underground mining support product. It has simple installation process and convenient use. It has strong anchoring force and tensile strength in underground mining and shotcrete support. It has Large force, strong expansion force.


Split set bolt has good supporting effect. Bolt support conforms to modern rock mechanics and surrounding rock control theory in terms of support principles, and belongs to active support. After the bolt is installed, the stability of the surrounding rock can be mobilized and utilized, and the bearing capacity of the surrounding rock can be fully utilized, and controls the deformation of the surrounding rock of the roadway effectively.so split set bolt can protect the stability of the surrounding rock of the roadway and improve the maintenance of the roadway.
