Abstract

The output of pulverized coal is one of the important factors affected the stability of continuous drainage of coalbed methane wells. We summarize four monitoring methods for pulverized coal concentration including the visual method without standards, the chromatometry with standard samples, the weighing method and the monitoring method. The static factors of coal reservoir and dynamic factors of coalbed methane development affecting the pulverized coal output of Linfen block are investigated. According to the continuous monitoring data of output of pulverized coal in Linfen block, the relationships are established among the concentration of pulverized coal and the thickness of tectonic coal and the casing-pressure using the method of logging interpretation and regression analysis.
