Equipment Performance Requirements of the Multi-Functional Roof-Bolter, Present Situation and Development Trend

Roof-bolter is a very important drilling equipment in anchor bolt support engineering construction, which affects the quality and speed in supporting engineering seriously. The different support engineering should choose different models of roof-bolter. Domestic roof-bolters are split-type, torque small, body bulky, inconvenient mostly, and foreign roof-bolters are advanced functionality and performance, but expensive. This paper deals with the geotechnical anchorage engineering application characteristics and requirements of drilling equipment, the roof-bolter research status, multifunction roof-bolter technical condition and its development trend, analyzes the gap between domestic roof-bolter with foreign roof-bolter. It is of great significance to develop new multifunctional roof-bolter in China.
