Galvanized Mechanical Expansion Shell for Harsh Coal Mine Rock Bolts
Product Details
Expanding shell anchor heads are used for roof and rib support in mining working areas. As an independent or auxiliary anchor support system, they can also be used to connect various components of mining equipment. Common specifications are 32mm, 35mm, 38mm, 42mm and 48mm. The material is cast iron and the surface treatment is sandblasting. Can be anchored in any rock formation, providing adequate anchorage. They are designed for anchoring in soft soil or hard rock. In good formations, the anchorage exceeds the ultimate strength of the steel anchor. All expansion shells require adequate formation in the anchorage area. The suitability of the anchorage and expansion shell used is best determined by physical load testing. The expansion shell is easy to install and instantly supports the work area by turning the bolt to create a point to anchor it in the hole. The casing is anchored to the rock, creating tension at the bottom of the borehole that transfers the load from the bolt head and plate to the rock through the casing.
