In recent years, coal machine manufacturers, which are large and small, all over the country and all over the world, are invested in development teams of heading and anchoring machines. At present, the digging and anchoring machine used in China mainly comprises a two-side digging and anchoring machine, a gantry type digging, anchoring and protecting integrated machine and a connecting and anchoring machine.

The two-side type tunneling and anchoring machine mainly takes the existing tunneling machine as a platform, utilizes a cutting part of the tunneling machine, and completes the connection of an anchoring and protecting part and the tunneling machine by replacing the pin shafts of the cutting part, a rotary table and a cutting lifting oil cylinder, when the anchor rod drilling machine works, the upper position, the lower position, the left position and the right position of the anchor rod drilling machine need to be adjusted by means of the cutting part, and the anchor rod drilling machine completes the anchoring and protecting work by actions such as self swinging, rotation and the like. It has the specific disadvantages that: the anchor rod drilling machine is easy to scrape and damage the upper; when the anchor rod is driven, the cutting part can not fall to the ground, and the safety requirement is not met; the empty-top distance is large, and at least one row of anchor rods are empty-top; the anchor rod positioning efficiency is low; the adaptive range is narrow.

But still have some problems, for example shelter from cutting operation sight, main arm telescopic distance big pipeline is difficult to arrange scheduling problem. At present, the method is still in an industrial test stage and is not popularized and used.

The anchor connecting machine integrates an anchor rod drilling machine on the basis of a continuous mining machine, and can theoretically realize synchronous cutting and supporting operation, thereby improving the working efficiency. However, the working position of the anchor rod drilling machine is far away from the foremost end of the equipment, and the machine body is large, so that the machine is only suitable for working conditions of large empty-roof distance, large roadway size and small coal rock hardness. The vast majority of domestic coal mines cannot meet the conditions. And from the practical point of view of the application, this machine is when normal work, and efficiency is higher. However, the equipment is too complex, is imported basically and is high in price, and a great amount of manpower and time are needed in the process of dismounting and debugging the equipment underground. In conclusion, the cost performance of the machine is not high, so that the market sales occupancy is small.
