Intrinsically Safe Linear Sensors for Mining Environment

The SAFDY solid-state airflow sensor is a proven way to accurately measure airflow in mines, independent of small particles. It was originally designed for use in South African diamond and coal mines to monitor the airflow underground and to determine whether the ventilation system – crucial for human life – was functioning.

Infra-red sensors provide some advantages over the conventional heat of combustion sensors that are generally used for mining applications. As methane absorbs infra-red light very strongly at characteristic wavelengths, infra-red sensors are usually used in other areas where methane detection is required. They also provide faster response times and potentially have longer service lives when compared to heat and combustion sensor alternatives.

Coal Mining: MSHA requires O 2, CO and CH 4 to be monitored continuously, therefore these sensors must be present in all coal mines. NO 2 sensors may be added, depending upon the specific application. Metal/Non-Metal Mining: LEL or CH 4, O 2 and CO are commonly required for these mining applications.

Using Strain Gauge Bolt-On Strain Sensors In Mining

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7) decommissioning the mine and releasing the property for post-mining use.
