2015年,梨园矿宁庄井为给一线职工创造整洁舒适安全的作业环境,狠抓煤尘治理,优化井下巷道测尘、喷雾降尘、净化通风等综合防尘设施,取得了较好的效果。近日的测尘结果显示,综掘工作面总粉尘浓度从45毫克/立方米降至10毫克/立方米,采煤工作面总粉尘浓度从18毫克/立方米降至5.5毫克/立方米。为降低粉尘浓度,减少不安全因素,确保防尘工作落到实处,该井多次召开防 In 2015, Lianyuan Mine Ningzhuang wells to create a clean and comfortable working environment for front-line workers, pay close attention to coal dust control, optimization of mine roadway dust, spray dust, clean ventilation and other integrated dust-proof facilities, and achieved good results. The results of recent dust tests show that the total dust concentration in the fully mechanized heading face is reduced from 45 mg / m3 to 10 mg / m3, and the total dust concentration in the coal mining face is reduced from 18 mg / m3 to 5.5 mg / m3. In order to reduce the concentration of dust and reduce insecurity, to ensure that dust-proof work is implemented, the well held a number of anti-
