In these projects, the boring machines drill through rocks characterized with different properties. In coal mines, coal is one of the major types of sedimentary rocks with low uniaxial compression strength (UCS) (<120 MPa). The drilling depth in coal mines can reach 600 m, and the maximum diameter of back reaming reaches 5 m.

This paper describes an autonomous loading system for loadhauldump (LHD) machines used in underground mining. The loading of fragmented rocks from draw points is a complex task due to many factors including: bucketrock interaction forces that are difficult to model, humidity that increases cohesion forces, and the possible presence of boulders. The proposed system is designed to integrate ...
