Drilling & Blasting Cost per Ton in Mining – Complete Technical Guide with Calculation Method (2026) Drilling & Blasting Cost per Ton is one of the most critical performance indicators in both surface and underground mining operations. It directly affects mine profitability, production efficiency, fragmentation quality, equipment performance, and overall operating cost. In this professional mining engineering guide, we will break down drilling and blasting economics using real-world formulas, technical logic, practical examples, and proven cost optimization strategies used across global mining projects. Why Drilling & Blasting Cost per Ton Matters in the Mining Industry Drilling and blasting is the first production stage in hard rock mining. Any inefficiency here multiplies cost across loading, hauling, crushing, and processing. Controls rock fragmentation Impacts excavator productivity Reduces crusher energy consumption Determines overall mine profitabil...

Dump Truck Productivity & Cycle Time Calculation in Open Pit Mining (International Method) Dump truck productivity calculation is one of the most important topics in surface mining operations. Mining engineers in the USA, Australia, and Canada use standard cycle time methods to estimate hourly and daily production. This guide explains dump truck productivity formulas, cycle time components, and practical calculation examples. ⛏️ What is Dump Truck Productivity? Dump truck productivity means the total quantity of material transported by a truck fleet in a given time (usually per hour or per shift). It depends on cycle time, payload capacity, road condition, and operational efficiency. 🔄 Dump Truck Cycle Time Components Loading Time Haul Time (Loaded) Dumping Time Return Time (Empty) Spotting & Delay Time Total Cycle Time = Loading + Haul + Dump + Return + Delay 📐 Dump Truck Productivity Formula Production per Hour = (Truck Capacity × Fill Factor × Efficie...

MSHA Safety Rules for Underground Coal Mines – Complete Guide (2026) MSHA Safety Rules for Underground Coal Mines – Complete Guide (2026) Mining is one of the most hazardous industries in the world, especially underground coal mining. To protect miners and ensure safe working conditions, the United States government established MSHA – Mine Safety and Health Administration . MSHA enforces strict safety regulations to prevent accidents, explosions, health hazards, and fatalities. In this guide, you will learn: Ventilation rules, roof support standards, training requirements, inspection procedures, emergency preparedness, and MSHA penalties. What is MSHA? The Mine Safety and Health Administration (MSHA) is a federal agency under the U.S. Department of Labor responsible for regulating mine safety across coal, metal, and non-metal mines. Main objectives of MSHA: Prevent mine accidents and explosions Reduce occupational diseases Ensure compliance with safet...

Continuous Miner in Underground Mining: Working, Parts & Production Continuous miner is a highly productive underground mining machine used mainly in coal and soft rock mines. It cuts, loads, and transports material continuously. What is a Continuous Miner? A continuous miner is an electrically powered machine that uses a rotating cutting drum to excavate material without drilling and blasting. Main Parts of Continuous Miner Cutting Drum Gathering Arms Conveyor System Electric Motors Hydraulic System Crawler Tracks Working Principle Cutting drum breaks coal/rock Gathering arms collect material Material transfers to conveyor Discharged into shuttle car or conveyor belt Production of Continuous Miner Production depends on seam thickness, rock hardness, and system efficiency. Typical Production Coal: 15–30 tonnes/minute Highly mechanized panels: Higher output Advantages No drilling & blasting High productivity Continuous operation Reduced ma...
