摘要

Presented a new coal dust control program that was airtight negative pressure dust-control technology at the transpersite, combining with analysis with the movement of air currents and numerical simulation of gas-solid flow at the transpersite, and proved the mechanism of precipitation and proliferation for coal dust-controlt in theory. The technol-ogy has made good economic results at the Heidaigou Clean Plant, not only dust concen-tration control within 10 mg/m3 to the work site, but also substantial energy savings and cost savings.
