輸煤皮帶巷運(yùn)煤量對(duì)揚(yáng)塵運(yùn)移擴(kuò)散影響的數(shù)值模擬
[Abstract]:In order to understand the distribution of dust during coal transportation in coal conveyance belt roadway and to explore better dust removal technology, taking the main inclined coal conveyance belt roadway of a large coal mine as the research background, a three-dimensional model is constructed and based on the theory of gas-solid two-phase flow. A two-fluid model was used to simulate the three-dimensional distribution of dust concentration under different coal transport volumes. The results show that the increase of belt coal transport volume increases the friction area between coal flow and air flow and the wind speed of roadway section, increases the dust intensity, expands the area of high concentration and remarkably increases the dust pollution degree in the middle and lower space of roadway. The influence of coal transportation on dust concentration decreases with the increase of the distance from belt to belt, and in the design of wet dust removal, the dust removal effect can be improved by the linkage between automatic spray system and coal quantity monitoring.
