HOW CAN OPERATING COSTS IN SURFACE MINING BR REDUCE THROUGH DRILLING AND BLASTING OPERATION  This article is divided into the following subtopics: 1. What is mine operation cost? 2. Key factors that affect operation cost 3. Drilling and Blasting operation influence on operation cost. 4. How to optimize drilling and Blasting to minimize operation cost. BRIEF ON MINE OPERATION COST  As a Mining Engineer working in a mine, we are all concerned about safety first then profit and constant cash inflow. It obvious that, if their is no profit then there is crisis as this will be a tunnel to salary payment delay and even lost of our company customers. " As continuity is the code of Continuous demanding" MINE OPERATION COST: This is define as the total cost incur to produce a unit ton of an ore from the earth crust. OPERATION COST IS DIVIDED INTO THREE 1. LABOUR COST 2. RAW MATERIAL COST 3. MISCELLANEOUS COST 1.Labour cost is the cost incur to compensate human effort as con...

By GIANT MINER Saturday ,26th of March 2021 Mining as an operation that involves the Exploitation of valuable ore or rock from the earth crust must be carryout at safety to health and to the environment (including general public). Mining operations both surface and underground should be  such that is environmental safe and not causing hazard to workers and general public health and safety. Taking a transparent look at the  Nigeria Minerals and mining Act 2007 and the Nigeria Minerals and  Mining Regulation 2011, the chapter 1, part iv Section 4(j), and its Regulation 2011 section 3(b) empowered and state the obligation of the Nation Minister for Mines and steel development to ensure that a measure is put in place to ensure that the welfarism and safety of all workers and general public relating with mineral operation is garantee. The section 17(b) of the ACT and the Section 5(2)(h) of it regulation make it as an obligation to the mine inspectorate Department MID to superv...

Technical article By: Taiwo Blessing olamide INTRODUCTION Blasting result assessment is very important to justify the efficiency and Productivity of every blasting operation. This is also to view the need to optimize the blast design in order to add value to downstream operation and reduce the cost of transporting run-off-mine, prevent transportating waste materials www the mine to the mill, minimize the cost of crushing and separating the gangue material from the concentrate in case of metallic and gemistic mining industries. It become important that analysing the blasting result using various available software that helps the mine manager to meet up with the production rate per day at the lowest cost implication is imperative. Most mines are less concerned about the result of Blasting but still keep complaining on the low profitability of their mine and low efficiency of the working equipments. Poor loading with long loading cycle time along side with continuous separation of Boulder...

Mining Engineering is the best field to be as we are concern with how the valuable Mineral deposit is Exploit from the earth crust for the benefit of manufacturing man's want. Working bench and safety issue Working ore deposit on a single bench may likely be hazardous if proper care is not taken to check Safety management. The failure of rock depend strictly on the bench slope angle and the discontinuity condition of the rock. Appearance of fracture and fault Vin rock mass can result from natural features and also artificial factors including poor Blast design, poor mine design among other issue relating to mining operations. To avoid such accident like truck failing, Rolling down of boulders from level to level it important to ensure benches are wide enough and design with sufficient beam. A beam is a safety distance space left at both front and edge of a working bench width and haulage vroad (Ramp) to safely guide haulage trucks from failing into the pit and also guid...

Safety tips in Explosive transportation and storage Explosive is sincerely known to be highly dangerous due to the high energy emission at detonation. Explosive can either undergo detonation or deflagration, Depending on the type of Explosive, the intensity of the initiation energy and the present condition and sensitivity level of the Explosive. Explosives had been design from manufacturer production point to be safe under some specified conditions. For this reason, explosives are classified into high and low Explosive base on sensitive and energy Strength. It also classified into primary, secondary and tertiary Explosive base on its working principle. Some country also further classify Explosive into class 1, 2... All this attempt was to ensure good Safety storage and proper handling understanding. Most Explosive may become unstable under temperature, handling status, environmental condition and storage.  Having the knowledge and understanding of Explosive is not limi...

MISFIRE DEFINITION  An explosive charge in a drill hole that has partly or completely failed to explode as planned. Causes include unskilled charging; defective explosive, detonator, or fuse; broken electric circuit or--most dangerous--cutting off of part or all of the charge through lateral rock movement as other holes in the vicinity are fired. Stringent safety precautions cover procedure in minimizing these risks and in dealing with known or suspected misfires. A smoldering fuse may delay explosion, causing a hangfire, so return to workings after a suspected failure is necessary. Another main cause of accident is drilling into or dangerously near a socket--an apparently empty drill hole. Rules for misfires ( MMMR-2002) A.When a misfire occurs in a mine, indicated by the counting of exploded shots in case of fuse blasting, or observed by the blaster from other indications in case of electrical or detonating cord blasting, no person shall enter the place of blasting un...

Drilling is the creation of Artificial cavity into rock for the placement of Explosive. Drilling can be done for different purpose ranging from: 1. Rock Blasting 2. Oil and gas production 3.rock stability and Safety purpose 4. Exploration purpose  5. Water and borehole drilling 6. Among others. Drilling for rock Blasting is done for the loading of Explosive into the rock formation so as to generate the shock and gas energy require to fragment the rock mass. Planning for an event makes the event or operation more perfect and productive. The condition of the drill holes and arrangements in place of pattern design of the hole drilled for Blasting has great impact on the effectiveness of the blasting. Some of the parameters that explains the status of blast holes are: 1. Burden: the perpendicular distance between the first drill holes row to the nearest free face. Or in others way, the distance between two adjacent  Hole rows.this affect distribution of energy wit...
