摘要： The invention provides a method and apparatus for electronically testing the safety of sources of energy such as electrical circuits, in explosive atmospheres such as high risk mining situations, using an electronic spark tester (EST) in place of the known mechanical spark test apparatus (STA). The EST typically uses an analogue subsystem (5) and a digital subsystem (6) connected by a digital to analogue converter (7) and an analogue to digital connector (8) to apply a simulated spark load to the energy source and measure the time varying current response to that load.

摘要： The invention provides a method and system for monitoring the flow of ore in block cave mining operations by inserting an active magnetic transponder 1 into the ore body 12 and generating an alternating magnetic signal with the transponder 1. The ore is monitored with a magnetometer (14, 15, 16, 17, 18) to detect the magnetic flux emitted by the transponder 1 thereby determining the position of the transponder. Successive recordings of the position of the magnetic transponder are taken as it moves along with the ore as it "caves". In this way, the flow patterns of the ore may be revealed.

摘要： An underground mine communication system using underground mesh nodes (4 and 5) connected by mesh communication paths (6) which are typically conventional wire line or line of sight wireless communication paths, is connected to a number of higher level receiver stations (7) in locations corresponding to the nodes (4) by way of through the ground wireless communication. The through the ground wireless communication may be implemented by way of magnetic loop antennae at corresponding locations (4) and (7) or by way of earth current antennae. The system provides numerous redundant pathways in the mesh, allowing communication to continue even when various mesh communication paths (6) are disrupted or destroyed by emergency situations.

摘要： A personal emergency communicator (1) able to be readily carried by an underground miner, generates a signal transmitted through the ground via a ground antenna where it can be intercepted and received by a through the ground receiver equipped with an equivalent antenna. In one form, the ground antenna comprises an earth current antenna provided by ground engagement spikes (6) receiving the signal from the communicator (1) via wires (5). The signal is preferably digitally generated from a keypad (3), shown in a screen (4), and the device may be powered by a battery or a crank and generator assembly (2). In an alterative form, the ground antennae are provided in the form of a loop antennae.
