What is coal log pipeline (CLP)?
Coal log pipeline (CLP) is an innovative emerging technology for coal transportation using pipelines. In the process of CLP, coal at the mine is first compacted into cylinders (logs) of a diameter 5 to 10% smaller than that of the pipe through which the coal logs are transported. The length of each log is usually twice the log diameter. Water is used to suspend and transport the logs through the pipe.
