Mine is the area which people exploit the mine resources, it can be divided into the underground mine and the open mine. Underground mine is far from the earth’s surface, it usually needs people to exploit mine from the underground. Open mine nears to the surface, people can dig mine directly. But most of the mine is belonging to the underground mine. The area is large, which includes the ground, underground, and the surrounding facilities’ areas. To prevent the collapse of the mine and the surrounding terrain, the protecting measure is very important.
Sinorock provides two different types of self-drilling anchor bolt system, which both includes various diameters to bear a large range of ultimate load and yield load. we adapt different drill bits to suit for the different conditions during the construction and the digging of mine. Under the precondition of stability, the productions are safe, efficient, energy-saving and environmental friendly, and then they will create good benefit.

Self drilling hollow anchor bolt is suitable for the broken rock, loose soil and conditions which are difficult to drill holes, such as fracture zones, decayed rock, gravel, sandy gravel, backfill ground. It is an anchor bolt which combines the drilling, grouting and anchoring together and it has the features of reliable, efficient simple and safe.
Duplex coating rock bolt combines two different protecting ways together: hot-dip galvanizing and epoxy coating, which forms a coating and to prevent rusting. It doesn’t react with acid, alkali and it can separate water, oxygen, chloride and other corrosive medium.Then it can reach the good result of corrosion prevention.
Combination hollow bolt is a new kind of anchor bolt. It combines of hollow anchor bar and solid anchor bar. This two parts are connected by coupler.There is a slurry channel on the connection section and it has the good stiffness and shearing strength. This kind of anchor bolt takes full advantages of hollow anchor bar and solid anchor bar. It is efficient, practical and economical.
Fiberglass anchor bolt is made of superior resin, alkali-free glass fiber yarn and other auxiliary materials through special process. It is a new kind of all thread bolt, which consists high strength composite plate and nut. This kind of product is specially suitable for fully-mechanized coal mining . It not only ensures safety of under coalmine operation, but also can be used for the supporting of mine.I t helps to improve mining efficiency greatly, reduce the damage of cutting pick of coal cutter and save production cost.

In a word, based on the different geological conditions, our company develops and makes different anchor bolt productions and to reach the best effort and afford our customer the beat one-stop service.
Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein,seam, or reef, which forms the mineralized package of economic interest to the miner.

Sinorock provides self drilling anchor bolts for various kinds of mining projects. We can also customize the products according to the requirement of clients. Thanks to the advanced mining technology with self drilling anchor bolt, the modern practices have improved safety in mines significantly.
