The mechanism of floor heave was analyzed by establishing mechanics models and solving differential equations.The amount of floor heave is proportional to the abutment pressure of surrounding rock,roadway width,and the distance of support pressure peak to the roadway and is inversely proportional to the elastic modulus of floor rock.Using FLAC2D to simulate floor rock grouting in soft rock roadway verifies the active role of floor rock grouting in the floor controlling of soft rock roadway; floor rock grouting and grouting range directly impact on the stability scope of surrounding rock,namely,with the increase of grouting range,the subsidence of roof,the approach of both sides,and the amount of floor heave decreased gradually,the stability of surrounding rock is enhanced.
