摘要
煤矿开采沉陷的预计参数大都是根据移动盆地走向和倾向主断面上观测线的实测资料求得。针对非规范岩移观测站和非主断面实测数据不完整的情况,文中在尊重岩移观测站实测数据的前提下,以概率积分法预计参数求解为例,提出了根据非规范观测线实测数据解求、FLAC3D数值模拟计算、地表变形预计程序分析拟合验证和相邻采区已有研究成果参照的联合求参方法,所求取的岩移参数能精确满足实际生产的需要。
Prediction parameters of mining subsidence used to be solved according to the actual measurement data of an observing station along the principle strike-inclination subsidence sections. Focusing on the non-principle subsidence sections and incomplete measurement data of an observing station, and taking the processes on estimating prediction parameters of probability-integral method for example, a new feasible method is probed for computing these parameters combined with calculating from the incomplete measurement data, fitting-validated analyzing by subsidence predicting program, numerical simulation computing based on FLAC3D and referencing to the existing research results of neighboring regions. The study results are confirmed that these prediction parameters can well meet the needs of practice productions in mining.
