The Martin ® Surfactant Dust System applies surfactant agents using a fully automated system to maintain consistent treatment application while avoiding surfactant agent waste. The actual details of the surfactant application are determined by the needs of the customer and the specific environment. Each system is custom engineered to match your operating requirements.
Coal dust — an unavoidable byproduct of coal mining — adds a combustion or explosion risk in any underground mine. Federal and state safety regulations mandate that any coal dust be diluted with powdered limestone, also known as rock dust, to minimize the and distributing large volumes of rock dust to underground mines presents an interesting logistics challenge.

The Miner is added by IndustrialCraft 2 as an automated mining solution. It requires a Low Voltage input (32 EU/t), many Mining Pipes, and a Mining Drill or a Diamond Drill to function. If you use an OD Scanner or an OV Scanner, it will branch to the sides to collect ore blocks. Without these scanners it will mine a 1x1 shaft straight down.
In mining, optimal lubrication is of the greatest importance to prevent excessive wear and tear of pins and bushings and to keep out dirt, dust and water. Groeneveld''s heavy duty automatic lubrication systems can be equipped with extremely strong lines and extralarge reservoirs in order to meet the lubrication demand.
In Australian openpit mining, fine coal dust is extracted from watercoal dust mixture with a temperature of 25 °C. "For this purpose, the mixture is first fed to horizontal belt filters," says Steve , Business Development Manager at NETZSCH Australia Pty Ltd. Until August 2017, two centrifugal pumps were used for decanting the excess water.
