Microprocessor-assisted shaft signal system (MASS)

Scope of application and purpose

Microprocessor-assisted shaft signal system (MASS) is intended to coordinate personnel actions and to control a hoist while lifting people, cargo, or oversize items up and down, or while inspecting or servicing the shaft or the head frame. The MASS systems are intended for passenger, cargo, and skip container hoists at the mines, where:

Number of landing platforms: max. 2
Number of levels (work stations): 12

Conveyance control and indication system

Scope of application and purpose:

The conveyance control and indication system (the System) is intended to coordinate the actions of the hoist operator and service personnel while inspecting the shaft, monitoring the conveyance sensors status, and issuing control signals to the hoist circuit.

Application: to control actuators; to monitor the status of sensors at the case, skip container, sinking stage or counterweight; to transmit and receive audio and digital data by a wireless channel in various modes of cage or skip work at mining sites.

Loudspeaker communication and warning system

Scope of application and purpose

The loudspeaker communication and warning system (the System) is intended for loudspeaker communication, warning, and process interlocks, as well as to provide functions required for the equipment control system at the loudspeaker communication and warning system installation site (intrinsically safe contactor switch interlock, sensor network control, timing, etc.) at underground excavations and ground premises of mines and pits with the ambient of hazardous gas and/or combustible dust. Furthermore, by means of a modem the user can control the system and downstream equipment from the surface, which makes diagnostics and repair less time- and labour-consuming.
