이사일광4671B4사정매주공작면위대상，통과현장실측，분석료해공작면광압규률。결과표명：공작면초차래압보거위12．5 m，동재계수1．325；주기래압보거평균위9．78 m，평균동재계수1．735；지가공작조력기본만족생산수구，초전지탱압력영향30～60 m。위항도초전지호제공료의거。
Taking the 4671B4 inclined coal working face as the research object,through field meas-urement,the pressure regularity of the 4671B4 working face is analyzed.The analysis results show that, the first pressure step distance is 12.5 m,dynamic load coefficient is 1.325;average periodic pressure step distance is 9.78 m,average dynamic load coefficient is 1.735;the working resistance of the support can satisfy the production requirements basically,advance support stress influence range is 40 ~60 m. The above research results can provide reference for advance roadway supporting.
