Equipment for effective demolition
Demolitions take place in mines during upgrades or at the end-of-life of a mine. In the case of a mine that has come to the end of its useful life, environmental aspects need to be taken into consideration in order to incorporate cleanup and reclamation of the sites.
These decisions can affect the schedule and cost of the demolition activities because they may control how the demolition contractor will conduct his activities. In the case of demolitions in order to upgrade facilities, the fact that it is a live site means that extra care and safety must be taken in order not to disrupt mining activities on the site both underground and above ground.
When sourcing for a demolition contractor, experience and track record should be key. Assess the qualifications of the personnel and peruse their past projects. Determine their suitability for your particular project because each project always has unique challenges. Even while the contractor may tout himself as the best in the market ask for a list of references of satisfied customers. When it comes to the type of equipment, we take a look at some of the companies and what they have to offer.
BTI manufactures and distributes a wide range of mine, quarry, construction and demolition equipment. Specializing in hydraulic hammers, mobile rock breakers, stationary and portable rock breaker systems, construction and demolition attachments, BTI is also well recognized for their full line of underground utility vehicles including mobile scalers, scissors lifts, crane trucks, lube trucks, anfo loaders, shotcrete mixers and placers, cassette systems and personnel vehicles. Applications range from primary and secondary sites involved in construction, demolition or recycling, to quarries and underground mining operations such as scaling and explosives loading.
Technology plays a critical role in the company’s continued successes. BTI enjoys a reputation for engineering products with the most advanced technologies available, yet the resulting systems are remarkably easy to use. Its breaker systems, for example, literally have benchmarked reliability and performance across a broad range of applications. Similarly, its hydraulic breakers use sophisticated technology to produce a simple design. With only two internal moving parts, this line of breakers and attachments makes the operation of hydraulic equipment easy, flexible and reliable. Field-proven and customer-sanctioned, BTI products are enthusiastically accepted as the standard for the industries they serve.
For the larger stationary crushing plants, BTI has designed and developed TTX Series Rock breaker System. This system is used in applications where extremely hard rock is present or a large coverage area is required. It can be used for material handling applications. Systems can be equipped with a 4,000 to 10,000 ft-lb class breaker, models available with up to 45 ft Nom. Horizontal Reach (with breaker vertical).Features and benefits of TTX series rock breaker system include: high strength steel (bent, 4-plate) construction 65 ksi tensile strength; 50 ksi yield strength for longer service life, reinforced pivot and mounting pin joints from improved durability, hardened steel bushings in pivot joints and larger diameter pivot pins provide reduced bearing pressure and increased service life, thick pedestal base plate – 2.0” (50 mm) for stable mounting – optional concrete installation available, sealed turn-table bearing and gear drive for longer service life, increased cross sectional strength of boom and dipper where high stress is realized and can-bus (iqan) control technology for more precise control and ramping for improved operation response.
BTI’s Low Profile Mobile Breaker Systems eliminate disruptive, costly and unsafe blasting in stopes, draw points and grizzlies, providing efficient, safer alternatives to secondary blasting.

BF CARR’S & ASSOCIATES.
BF Carr’s main product is the Stem Plug Blast Control Plug which is the original, most widely used, and most effective stemming plug on the market. First introduced in 1991, well over 4 million plugs have been successfully used worldwide.
Stemplugs work by creating a blockage effect in the borehole by wedging the stemming material between the borehole wall and the plug. It is a similar situation to plugging up a rifle barrel. Upon detonation the plug is forced upward and moves approximately 1.5 to 2 diameter lengths prior to ‘locking up’. When the plug seizes in the borehole the blasting energy is contained in the rock where it belongs. There are numerous studies documenting the effect. Fragmentation and Fracturing are increased, while fly rock, air blast, and dust are decreased.
Stem Plugs are loaded on top of the explosive and below the stemming material. At detonation the whole column begins to move up and the plug wedges the stemming material against the borehole wall and “locks up”. The rapidly expanding gasses are contained in the bore hole leading to a better blast – less wasted energy contributing to fly rock, air blast, etc. They also have Max-Blast TM Stemming Plugs which are the most effective vinyl plug on the market. The patented “positive seal’ accordion design forms a barrier that prevents the explosive gasses from passing up through the stemming material. When the stemming material is undisturbed by rapidly expanding gas it will bridge and lock up in the borehole.
Their Plugs, when used in well designed blasting programs, will increase fragmentation from 20percent to 50 percent while decreasing Air Blast, Fly Rock, and Dust. They offer the two best stemming plugs on the market in the sizes most frequently used in the Mining and Aggregate Industries.
