为了改变工作面超前支护距离确定的盲目性，选择使用KSE-Ⅱ钢弦测力系统进行现场测试，经分析得出了综放工作面超前支承压力影响范围，在后续开采的综放工作面开采中调整了两巷的超前支护范围，保证了回采安全，满足了通风和行人的要求，取得了较好的技术经济效果。
為瞭改變工作麵超前支護距離確定的盲目性，選擇使用KSE-Ⅱ鋼絃測力繫統進行現場測試，經分析得齣瞭綜放工作麵超前支承壓力影響範圍，在後續開採的綜放工作麵開採中調整瞭兩巷的超前支護範圍，保證瞭迴採安全，滿足瞭通風和行人的要求，取得瞭較好的技術經濟效果。
위료개변공작면초전지호거리학정적맹목성，선택사용KSE-Ⅱ강현측력계통진행현장측시，경분석득출료종방공작면초전지승압력영향범위，재후속개채적종방공작면개채중조정료량항적초전지호범위，보증료회채안전，만족료통풍화행인적요구，취득료교호적기술경제효과。
in order to change the blindness of advance support distance determination of working face, makes the determination of the advance support scope of working face has a scientiifc basis, choose the KSE-ii steel wire dynamometer system for ifeld testing, the analysis of the fully mechanized top coal caving face abutment pressure inlfuence scope, and adjust the advance support range of two lane in continued working face, guaranteed the safe mining, met the requirements ventilation and pedestrian, and achieved good technical and economic effect.
