为了研究非充分采动条件下的采动影响范围,在分析李宅煤矿非充分采动对马寨镇申咀村部分民房影响的基础上,提出"非充分采动影响范围调整系数"概念,通过求取概率积分法预计参数、充分采动系数综合计算非充分采动影响范围,并利用非充分采动影响范围调整系数来进行采动影响范围调整。研究结果表明:非充分采动条件下,利用概率积分法预计软件预计的开采影响范围与现场实际调查情况基本相符;非充分采动条件下,利用边界角计算的采动影响范围比实际情况大;根据概率积分法预计并结合充分采动系数能够很好地计算出非充分采动条件下的采动影响范围。

in order to study the nining ifluence scope under the subcrtical extraction conditon.based on the suberitical extraction in Lizhail Mine affected to the partial ivil buildings in Shenzuil Vllage of Mazhai Town a conception of " adjustment coeicent of the suberitial extracion infuence scoe" was provide.Waith the probability inegral method obtained applied to predict the parameters and the ill subsidence ceicient appied to comprehensively caculate the infuence s:ope of the subcrtical extraction,the " adjustment coefficient of the subcritical extraction influence scope" applied to adjust the influence scope of the mining.The study results showed that under the suocritical extacion condtfon.the mining infuence scope predicted with the sofware of the probatilit integral method could be basicall fied to the sie actual invesigation condt on.Under the sub.ritial extracion condton,the mining infuence scope calculated with the boundary angle would be larger than the actualcondition.Lccording to the prediction with the probatilty integral method and in combination with the ful ubsidence coeficient, the mining infuence scoe under the subcritical extraction condition could be well calculated.
