TechServe Mining Services are equipped with software’s that produces various production blast optimisation designs and/or specialised blast designs depending on the client’s requirements. The designs include but not limited to:
Final Highwall Design
Sensitive Area Design (Vibration, Airblast and flyrock Control)
Box Cut Blast Design
Fragmentation Optimisation Design
For continuous improvement on blast results, TechServe Mining Services conduct drill and blast audits within the parameters of the blasting procedures or general good practices.
Approved tolerable/ acceptable deviations levels from the blast design is normally approved and provided by the client prior to auditing for compliance levels.
Any obvious deviations from the design are either corrected immediately or escalated for a decision by management before the blast is initiated.
AUDIT INCLUDES:
Blast is monitored and results are analysed to optimise the blast designs for improved results.
monitor and analyse the following:
Fragmentation Analysis and Boulder Count Report
High Speed Video Recording and Analysis
Vibration and air-blast monitoring and analysis
Blast fall out dust analysis
Face Movement Studies
Blast hole diameter and inclination measurements (quantify explosives overcharging)
Blast dust impact monitoring and analysis when blasting close to residential areas
Explosive’s Viscosity Measurements
Explosive’s Gassing Rate
Explosive’s Density Measurements
VOD Monitoring and Analysis
with explosives field performance data to increase the confidence in decision making during adjudication of explosive supply contracts.
To improve the overall downstream production costs, comprehensive optimisation of the drill and blast with drill and blast results while reducing downstream cost
With the vast experience in the opencast drill and blasting including explosives technology, TechServe Mining Services will assist its Clients to determine and understand the causes of undesired blast results in relation to the following:
an evaluation of the potential air blast overpressure, ground vibration, dust, fumes and flyrock impacts from the proposed blasting operations within the open pit mine on sensitive receptors located nearest to the Site. This will mainly focus on the following:
Pre – blast survey of residential and/or mine building to determine the structural Integrity
Blast impact on the ground water resource quality and quantity
Blast impact assessment on surface water resources quality
Noise and Fall Out Dust Impact Assessment
and upskill technical ability within our customer’s operations, the following topics are covered:
