Function Introduction
The bolter miner series products integrate tunneling, advanced temporary support and bolt support, and are high-end equipment for realizing rapid tunneling. Through the innovative support system design, the problem of "imbalance between tunneling and support" is solved, reducing auxiliary operation time. This series of products is suitable for integrated bolter mining operations under various geological conditions in large and medium-sized coal mines, adapting to various roadway tunneling processes such as one tunneling and one bolting, one tunneling and two bolting, one tunneling and multiple bolting, large-step long tunneling and long bolting, etc. It pursues complete sets, high efficiency, high safety and high reliability of the tunneling working face, improves tunneling efficiency, reduces personnel and increases efficiency, and explores complete sets of high-end intelligent rapid tunneling equipment for the whole process.
Structure Introduction and Technical Features
1. Adopts the original four-roof and two-side six-drill arrangement method. The drills move linearly to achieve rapid hole seeking. One person can control 2 drills at the same time, significantly improving support efficiency;
2. Has an original three-fold large support working platform (about 6㎡), which can stand more than 5 operators at the same time, greatly facilitating personnel to perform bolt mesh steel belt, bolt and cable support operations. The support personnel stand firmly, and movement is safe and convenient;
3. Quickly converts to support operations after cutting, with short unsupported roof time and small unsupported roof distance (≤300mm), good safety. Four roof bolt drills are close to the face, playing a good role in protecting the face;
4. One-key automatic deployment and retraction of the support system, one-key automatic centering of the cutting head, one-key automatic drilling, simplifying the workers' operation process, reducing auxiliary time, and greatly improving roadway formation efficiency.
