为安全回收煤柱,防止小窑采空区有害气体泄出,在对综采工作面采用均压通风过程中,造成总回压能升高,其他用风地点风流方向发生变化,使通风系统存在安全隐患。针对此种现象,通过利用JFY-2型矿井通风参数仪对受影响区域内各点压能进行测定,利用增阻法改变各用风点处压能,使通风系统恢复稳定,确保矿井安全生产。
為安全迴收煤柱,防止小窯採空區有害氣體洩齣,在對綜採工作麵採用均壓通風過程中,造成總迴壓能升高,其他用風地點風流方嚮髮生變化,使通風繫統存在安全隱患。針對此種現象,通過利用JFY-2型礦井通風參數儀對受影響區域內各點壓能進行測定,利用增阻法改變各用風點處壓能,使通風繫統恢複穩定,確保礦井安全生產。

For the safety recovery of coal pillar, preventing hazard gas from gob to leak, in the fully mechanized face pressure ventilation process, increasing the total return air pressure energy resulted in other using wind place wind direction changes, so that the ventilation system has great potential safety hazard. in view of this phenomenon, on the pressure energy of the affected region was measured by using JFY-2 type of mine ventilation parameters instrument, taking reasonable use of the method of increasing resistance to change the use wind point pressure energy, so that the ventilation system restore stability, and ensure the safety production of mine.
