China 42Mm Friction Bolt,Split Set Bolt supplier & manufacturer, offer low price, high quality Mining Bolt,Split Set Rock Bolts, etc.
Split set bolt is also called "Split Set Stabilizer". It was successfully developed by American Professor Scott in the early 1970s. 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.
Split set bolt has simple installation and labor saving. It uses fewer supporting materials and lighter weight than other bolts. When tunneling, the transportation volume of supporting materials is reduced, and the labor intensity is greatly reduced, which is conducive to improving the efficiency of tunneling.
