Control technology and development direction of coal mine dust from the 14th Five-Year Plan Period

In order to effectively prevent and control coal mine dust and improve the working environment of mines, this study discusses the latest progress and practical application effects of China's coal mine dust control technologies and equipment during the 14th Five-Year Plan Period. The specific details could be described as the dust control in fully mechanized mining face, dust control and dust removal in return airway of fully mechanized mining face, adaptive dust control and dust removal in long pressure and short suction of fast mining face, spraying robot and dust comprehensive treatment, monitoring of non dynamic light scattering dust, new electrostatic induction dust concentration monitoring, sedimentation dust monitoring, and comprehensive control of open-pit coal mine dust. As summarizing and analyzing the shortcomings of existing coal mine dust control technologies and equipment, this study provided prospects for the development direction of coal mine dust control technologies in China.
