Description

An all-in-one machine for digging and bolting

technical field

The utility model relates to the technical field of coal mine roadway excavation and support, in particular to an integrated machine for digging and bolting.

Background technique

China's energy reserves are "lack of oil, less gas, and rich in coal", so coal has long accounted for more than 70% of China's primary energy consumption. With the rapid growth of China's economy, coal consumption has also continued to increase. In 2013, coal production reached 3.7 billion tons. It is expected that the growth rate of coal consumption will remain at about 3% in the coming period. By 2020, the total national coal demand It will be around 4.8 billion tons. By then, the proportion of coal in my country's primary energy consumption structure will still account for about 60%. By 2020, the country's available coal production capacity will be 4 billion tons, with a production capacity gap of about 800 million tons.

With the development of science and technology in the coal industry and the requirements of my country's industrial policy, since the 1980s, advanced mechanized excavation equipment and bolt and cable support technology have been widely used in coal mine roadway excavation in my country. At present, the excavation equipment of large and medium-sized coal mine fully-mechanized roadways in my country mostly uses roadheaders, and most of the bolt and cable support operations rely on manual use of hand-held single-body bolters and coal electric drills for construction, and support operations take up a lot of time. The operating rate of the roadheader is less than 30%, and there are also problems such as low safety factor, high labor intensity, harsh working environment and low production efficiency under the roof during support. . Moreover, the structure of the single-body bolter is relatively simple, so the torque characteristics are poor, and the motor is easily overloaded. In addition, the bolt hole drill is a vertical operation, the motor is easily polluted by water, and the failure rate of the electrical part is high; in addition, The single-body bolter has a low degree of mechanization, a large workload, and requires workers to work in groups, so the efficiency of the single-body bolter is also low; and because it is usually operated under the exposed roof, there are serious safety hazards , and the locking force of the anchor rod requires secondary tightening.

The extensive use of fully mechanized excavators has enabled mechanized coal dropping and coal loading in the tunneling face, thus greatly increasing the tunneling speed. However, the support speed of the existing support equipment is relatively slow, and the support takes up two-thirds of the total excavation time, which greatly affects the production efficiency. Although there are four-arm drilling trucks and eight-arm drilling trucks on the market now, there are generally problems such as huge bodies, poor movement and passability in coal mine underground roadways.
