Civil Blasting
Drilling & Blasting
Drilling and blasting is a method used in mining and construction to break rock or earth. It involves drilling holes into the material and then using explosives to fracture it for excavation or construction purposes. We at N&M take great care to provide excellent drilling and blasting services, ensuring precise and controlled rock or earth excavation for various industries. Our experienced team employs the latest techniques and equipment to ensure safety, efficiency, and environmental responsibility in every project.
Secondary Blasting
Secondary blasting is a follow-up process to primary blasting in mining or construction. It fine-tunes the fragmentation of materials after the initial blast for easier handling and processing. N&M provides secondary blasting services for fine-tuning material fragmentation after the initial blast in mining and construction. Our expertise ensures materials are processed efficiently for subsequent use.
Trenching
Trenching involves digging narrow and deep channels or trenches in the ground. It's commonly used for laying utility lines, irrigation systems. N&M specializes in trenching services, offering expert excavation of narrow and deep channels for various applications. We take pride in delivering accurate and timely trenching solutions.
Road Cutting
Often blasting is required for the planned road to maintain a certain level or to excavate hard rock under the planned road surface thus ensuring better road preparation. The most challenging aspect of road cutting for any blasting company is blasting through slopes, hills or large rock formations.
Wind Farms
Wind farms are facilities that harness wind energy to generate electricity. They consist of multiple wind turbines strategically placed to capture wind power for renewable energy production. Our wind farm services involve blasting for the strategic placement of wind turbines to harness renewable energy. N&M contributes to the development of sustainable energy solutions.
Open Cast Blasting
Quarrying and Mining
This involves the excavation and processing of rocks and minerals for use in construction and manufacturing. Our quarrying and mining services take the fragmentation required by the client very seriously. We use special drill patterns to ensure our powder factor is sufficient to break the rock to the clients’ requirements.
Timing intervals during these blasting processes are particularly important to maintain the integrity of the high walls and to assist with the fragmentation.
Other services
Sensitive Blasting
Sensitive blasting is a blasting technique whereby we can blast close to infrastructure and services. It focuses on minimizing the impact of blasting on the surrounding environment or communities. With our techniques we are able to minimize the ground vibration and air blast pressure with minimum fly-rock.
Blast Design
Blast design is the process of planning and optimizing explosive blasts in construction or mining projects. It considers factors like safety, efficiency, and environmental impact to achieve desired results. N&M excels in blast design, meticulously planning and optimizing explosive blasts for construction and mining projects. Safety, efficiency, and minimal environmental impact are at the forefront of our blast design services, ensuring successful project outcomes.
Vibroreadings
Our equipment allows us to monitor ground vibrations and air blast pressure with ease and accuracy, which is crucial when blasting close to any structures, roads, sub-stations, and other infrastructure.
Non Explosive Demolition Agent
Non-explosive demolition agents are chemical compounds used to break rock without traditional explosives. They are a safer and more controlled alternative for breaking and demolition. N & M ensures precision rock breaking, making it an ideal choice for projects where blasting is not possible.
Breaking of Rock by mechanical means
Breaking rock by mechanical means involves the use of specialized machinery and tools to fracture or excavate rock formations. This method is chosen for its precision and reduced environmental impact, making it suitable for projects in sensitive areas or where explosive use is prohibited. We have specialised teams who have been trained in the use of this equipment.
Explosive transport
Our vehicles are all registered at the SA Police Services as “Dangerous Goods Vehicles” and we are thus able to - legally and safely - transport explosives from the various Manufacturers.
