薄煤层炮采工作面爆破多功能自动喷雾降尘系统的研制及应用

Development and application of multi function auto spraying and dust control system for blasting operation of drilling and blasting coal mining face in thin seam

根据兖州矿区薄煤层的赋存状况,利用采煤工作面只有一个爆破工作业,全工作面爆破过程中各区段(人为控制)存在时间差的特点,在减少工作面喷雾用水、不恶化工作面作业环境的情况下,采用PLC顺序控制、PLC+LCD集中监控的形式,研制成功了具有爆破前(后)自动洒水降尘和爆破时自动喷雾除尘两大功能的爆破自动喷雾系统。通过在兖矿集团北宿煤矿薄煤层炮采工作面的现场应用,取得了很好的降尘效果。

According to the deposit status of the thin seam in Yanzhou Mining Area,a coal mining face with only one blasting operation,with the time deferential features of each section（artificial control） in the coal mining face blasting process,under the condition to reduce the water for the water spraying in the coal mining face and not to be bad to the operation environment of the coal mining face,the PLAC program control and PLAC＋LCD centralized monitoring and control were successfully applied to develop the automatic spraying system for the blasting operation with the automatic watering and dust control before and after the blasting operation and the automatic water spraying during the blasting the operation.With the site application of the water spraying system to the thin seam coal mining face in Beisu Mine of Yanzhou Coal Mining Group,good dust control results were obtained.
