An arrangement and method of utilizing rock drilling information in a mine whereby drill holes are drilled in a surrounding rock material by a first mining vehicle. During drilling measuring data is produced and is inputted to a monitoring device for analyzing procedures. The monitoring device produces rock condition data of the rock material being drilled. The produced rock condition data is then implemented in a second mining vehicle.

The present disclosure provides a machine (100) for surface mining or road milling. The machine (100) is arranged to remove material from a ground region (102) while moving along the ground region (102) and comprises a ground engager for removing a portion of the material from the ground region (102). The machine (100) further comprises a detecting system (110) that has at least one detector element coupled to a component of the machine (100) to move with the machine (100) and arranged to detect at least one quantity associated with an electrical property of the ground region (102). The detecting system (110) is arranged to provide composition information concerning a composition of at least one material layer in the ground region (102) and thickness information concerning a thickness of at least one material layer (102a,b,c,d). The detected at least one quantity associated with the electrical property is used to provide at least one of the composition information and the thickness information.

The present invention discloses an acoustic emission monitoring and transmission system for engineering rock mass including an acoustic emission sensor and a ground workstation. The acoustic emission sensor is installed in a borehole of the monitored rock mass and transmits a received monitoring signal to the ground workstation through a cable. The acoustic emission sensor includes an acoustic emission probe, a probe installation mechanism and a transmission mechanism which transmits the probe installation mechanism with the acoustic emission probe to a setting position inside the borehole. The probe installation mechanism includes a shell connecting to the transmission mechanism and a probe sleeve for accommodating the acoustic emission probe.

A device for monitoring deep-sea sediment environment in mining polymetallic nodules is provided. The monitoring system includes: acoustic Doppler flow profilers, a self-potential probe, a turbidity meter and an underwater camera. The invention can realize long-term in-situ observation of sediment disturbance, and can realize the mechanical recovery of probe rod-type equipment without large-scale mechanical devices, thereby reducing the overall weight of the recovery equipment and increasing the probability of successful equipment recovery. Compared with the existing long-term in-situ observation equipment on the seabed, it is more environmentally friendly, efficient, energy-saving and reliable.
