随着机械化水平的不断提高,邢东矿综采工作面的产尘量越来越大,工作场所粉尘浓度居高不下,严重危害了职工的身心健康,矿井安全生产存在重大隐患。通过分析邢东矿综采工作面不同条件下粉尘运动的变化规律和喷雾系统的除尘机理,设计了综采工作面高压喷雾除尘系统。使用该除尘系统后,采煤机割煤时对于整个工作面平均全尘除尘效率达85%以上,呼吸性粉尘除尘效率可达75%以上;移架、放顶时平均全尘除尘效率达88%以上,呼吸性粉尘除尘效率达77%以上;回风巷水幕下风向5m处,其全尘除尘效率达98%,呼吸性粉尘除尘效率达95%。采用高压喷雾除尘系统在邢东矿综采工作面上防治粉尘取得了良好的效果。
隨著機械化水平的不斷提高,邢東礦綜採工作麵的產塵量越來越大,工作場所粉塵濃度居高不下,嚴重危害瞭職工的身心健康,礦井安全生產存在重大隱患。通過分析邢東礦綜採工作麵不同條件下粉塵運動的變化規律和噴霧繫統的除塵機理,設計瞭綜採工作麵高壓噴霧除塵繫統。使用該除塵繫統後,採煤機割煤時對于整箇工作麵平均全塵除塵效率達85%以上,呼吸性粉塵除塵效率可達75%以上;移架、放頂時平均全塵除塵效率達88%以上,呼吸性粉塵除塵效率達77%以上;迴風巷水幕下風嚮5m處,其全塵除塵效率達98%,呼吸性粉塵除塵效率達95%。採用高壓噴霧除塵繫統在邢東礦綜採工作麵上防治粉塵取得瞭良好的效果。
