The recommended calibration interval for most equipment, including seismographs, is one year. Across most of the North American territory and in many European regions, regulatory authorities require that seismographs are calibrated annually. This requirement has been or is being adopted by many other countries in the world, and certain projects require that seismographs are calibrated every three or six months.
Calibration is important for the tool to work as designed and to directly measure the actual vibration of the ground and the blow of the explosion. Although seismographs are designed for use on rough ground, they are nevertheless sophisticated electronic monitoring devices. Thus, preventive maintenance is an important part of the annual calibration process.
Some seismograph models are designed with geophone, microphone and data acquisition unit calibrated as a system. In general, this allows for the entire system to be calibrated more accurately. However, tools calibrated by this method are limited by the fact that the geophone and microphone match the data acquisition unit, and the sensors cannot be changed with those of other tools without affecting overall accuracy, even though they are of the same model produced by the same manufacturer. Other seismograph models are designed with the geophone, microphone and data acquisition unit calibrated as independent units.
It is in your best interest to have your seismograph calibrated by its manufacturer or its authorised agents.
Also, if a seismograph needs to be repaired, the manufacturer has the necessary experience and know-how to identify and solve the problem. At the same time, the manufacturer will make sure that spare parts comply with the specifications of the equipment. Unauthorised institutions do not have access to testing specifications, procedures or spare part lists, and they can use alternative spare parts that do not meet the functional requirements.
In order to achieve safe initiation and to prevent misfire, electric blasting circuits must be checked in terms of continuity and resistance before being connected to the firing source.
Control equipment for continuity of blasting circuits is used to check current flow. Such equipment only checks whether the circuit is closed or not. If the equipment does not indicate circuit continuity, it means that the circuit is interrupted and sections of it must be checked to detect the failure.
Specially designed and certified ohmmeters are used to check ohmic resistance of the circuit and circuit continuity.
CHRONOS type equipment
Trio Chronos is a high precision, portable digital chronometric device used for determining the delay accuracy of any detonators, fuse-heads, detonating relays and trunk-line delay connectors.
Trio Chronos also measures the detonation velocity of explosives, detonating cords and shock–tubes.
The device is suitable for use in the production and testing of explosives and in the military industry and in mining.
Electric initiation system
Blasting machines are portable devices that deliver the necessary energy to initiate electric blasting caps into the blasting system.
The devices currently used to initiate electric blasting caps use capacitors to store the necessary energy of the blasting system.
Blasting machines are operated with a special detachable key which, according to the supply source, actuates the alternator or provides the connection to the battery or the network.
The charge status of the load capacitor is indicated by a signal light. The capacitor is discharged and the stored energy is delivered to the blasting system either automatically when reaching the charge status or by rotating the key from the charge position to the explosion position.
In order to discharge the residual voltage of the load capacitor, blasting machines are provided with a fuse.
Blasting machines used in firedamp mines are additionally equipped with a locking relay that limits the impulse delivery duration of the detonator to 4 ms.
The maximum number of caps that can be initiated with a detonator is indicated on the label of the device or on the nomogram.
When using low-intensity electric blasting caps, the current is conveyed from the initiation source to the cap circuit through blasting cables that must be insulated and withstand a voltage of 2000 V.
For safety reasons, specific regulations provide that explosive charges should be triggered from a distance of at least 100 m.
In order to have low resistivity and high mechanical strength, blasting cables are made of multi-core copper and/or tinned steel, with a section resistivity of maximum 10 ohm/100 m. Cap circuits are usually connected with the wires of the caps; cap wire length must be chosen so that the connection of two neighbouring holes should not require extension lines. In special cases, for oversized blasting and isolated holes located far away from each other, insulated extension lines can be used in combined blasting systems (detonating cord and power supply).
In practice, low-intensity caps are initiated with ROY-type wire conductors.
Non-electric initiation system
Pyrotechnical means (pyrotechnical blasting caps and Bickford cord) or electric means (electric blasting caps) can be used to initiate NONEL-type non-electric systems or similar systems.
Also, specially designed devices (blasting machines) can be used.
The DS 2 blasting machine consists of a battery, a power amplifier assembly and a detachable chunk incorporating an electrode.
Both the electrode and the battery can be used for up to 1000 blasts, after which they must be changed.
Electronic monitoring system
The register of the stocks of explosives for professional use is designed for users who, in addition to the monitoring and localisation solution in compliance with the EU Directive, wish to digitally update their register of stocks instead of keeping it on paper.
The product includes the following components:
– robust 9” (22.8 cm) PC tablet (IP65 protection class);
– robust and user-friendly Bluetooth scanner (IP64 protection class);
– software for the register of stocks of explosives for professional use.
No internet connection or synchronisation with other devices is required to use the register of stocks of explosives for professional use. The application is autonomous and can run without a network connection. You can exchange data with the manufacturer/supplier by means of a USB stick that you connect directly to the PC tablet for goods entries.
Moreover, you can exchange data with the manufacturer via an internet-based Authorisation Centre or proprietary server as the PC tablet is provided both with WLAN (wireless local area network) and LAN (local area network) ports. Data are stored on the PC tablet in a database and are protected against both accidental and intentional changes.
To make a backup of the PC tablet database you only need network sharing for each location.
Access to the stock register data on a PC
A software will be installed on the PC to enable the user to access the stock register data. No extended authorisation is required to install this software. Software updates can be installed by the user with no extended authorisation for this software.
The user can install updates by selecting “check for updates” in the “About” screen with no additional authorisation. The software will restart automatically after the update is installed successfully.
Laser scanning equipment
Quarryman Pro is the laser scanning system of choice for aggregate quarries. It builds on 25 years experience of delivering laser-scanning solutions to the quarrying industry worldwide.
Quarryman Pro has transformed the safety and productivity of the quarry operations that have implemented it.
With Quarryman Pro you can scan a full rock face quickly, without the need of trained surveyors; the data can be used to plan:
– more accurate blasts, which eliminate the costs associated with explosives over-use;
– quieter, safer blasts that keep workers safe and have less impact on the environment;
– blasts with optimal fragmentation, thereby cutting transport costs for quarried rock, and minimising the waste associated with over-fragmentation;
– improved floor control, minimising wear on tyres and heavy mobile equipment.
It uses the structure and activity of the donor, the structure of exposed sites and duration of staff exposure to assess the level of safety.
Users have the possibility to operate with metric or imperial measurements and to import site maps or plans to facilitate the viewing of unit configurations and results.
