摘　　要：为了探明长壁综采膏体充填工作面充填开采后的地表沉陷情况,以高河能源E1302膏体充填工作面为实例,通过对地表沉陷因素的分析,运用等价采高的原理预计出E1302膏体充填工作面的沉陷参数,并通过MSPS预测软件进行了沉陷预测,预测值和实测值基本吻合,证明了膏体充填开采在长壁综采工作面的安全性和先进性。In order to find out the surface subsidence situation after filling mining in longwall fully mechanized mining paste filling face,taking Gaohe Energy E1302 paste filling face as an example,through the analysis of surface subsidence factors,the subsidence parameters of the E1302 paste filling face are predicted by using the principle of equivalent mining height,and the subsidence is predicted by MSPS prediction software.The predicted values are basically consistent with the measured values,it is proved that paste filling mining is safe and advanced in longwall fully mechanized mining face.
