摘要
以王坪煤业有限公司303盘区8307工作面为工程实例;在回采过程中各作业地点因粉尘浓度高,造成工作面能见度低、标准化质量差等;对工作面前期防尘措施及主要存在的问题进行了梳理分析;工作面拟改进综合防尘措施:安装泡沫抑尘系统,运输巷道拟安装全断面捕尘装置,卸煤点拟安装全封闭防尘装置;实际应用后,工作面内呼吸性粉尘浓度控制在14 mg/m以下,能见度提高至45 m,取得了显著应用成效。
Aiming at low visibility and poor standardized quality caused by high dust concentration in mining at 8307 working face of 303 Panel of Wangping Coal Industry Co.,Ltd.,the author makes a sorting analysis of the preceding dust prevention measures and main problems at the working face,and proposes the comprehensive dust prevention with installation of foam dust suppression system,full-section dust catching device in haulage roadway,and sealing dust removal at coal discharge point,which can control the respiratory dust concentration below 14 mg/m^(3),and improve the visibility to 45 m with remarkable application effects.
