Blasting being a primary operation in mining, quarrying and construction work, needs to be conducted as safely as possible. As it involves the use of explosives, it can result in the loss of men, material and money if not done rightly. Recent studies also show that fragmentation of the mine during blasting accounts for only 20-30% of the total amount of explosive energy used while the rest of the energy is wasted in the form of ground vibrations, flyrock and air-overpressure.<\/span><\/p>\n The main of any blasting project should be to minimise the production of non-useful energy. This is only possible with a well-formulated blast design. A good blast design should take into account many lesser-known factors like spacing between the feed holes, quality of detonators and flyrock.<\/span><\/p>\n Another major goal of blasting operation is a quality output in the most economical way. For example, using high quality and uniformly sized explosives might seem expensive at the start, but will greatly reduce costs in the end.<\/span><\/p>\n A guide to the right blasting plan will not only help you achieve the desired outcome but also save 20% on overall costs. To this end, there is no better guide than Uttam Blastech, with over 25 years of experience. From helping clients plan their blasting in a public area to supervising blasting in extremely challenging geographical areas, Uttam Blastech will leave no stone unturned for a safe and cost-effective blast.<\/span><\/p>\n Blast design\u00a0<\/span><\/p>\n Fragmentation analysis<\/span><\/p>\n Ground vibration and noise measurement<\/span><\/p>\n Explosive quality check<\/span><\/p>\n Blast performance optimisation<\/span><\/p>\n Environmental Impact Assessment (EIA)\u00a0<\/span><\/p>\n – Another challenge was to obtain all the permissions required to use the explosives as the area was terrorist infested at that time.

NTPC<\/td>\n<\/tr>\n \n \n Project and Constraint:<\/b><\/h4>\n<\/td>\n
When NTPC (Super Thermal Power Station) decided to expand their Super Thermal Unit at Ramagundam Super Thermal Power Station, the challenge was to excavate around 37,000 cubic meters of rock in a very critical area 20 metres away from their power-producing turbine which was also 6 metres away from a pump house that supplies water to the entire unit.<\/span><\/td>\n<\/tr>\n \n \n Our Approach:<\/b><\/h4>\n<\/td>\n
– The first challenge was to convince about the efficacy and the safety of the proposed methodology. A seminar was arranged with the team to address their concerns where it was agreed that the initial blast would be conducted at the farthest place as a trial.<\/span><\/p>\n \n \n Final Outcome:<\/b><\/h4>\n<\/td>\n
Once everything was in place, the work was executed in 37 days i.e. blasting and excavating, 1000 cubic metres per day, in spite of all the hurdles and concerns.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Read to know how Uttam Blastech saved DLF from all litigations during a blasting project in an area with historic properties (sensitive to low-level vibrations)<\/i><\/b><\/h3>\n
