The Determination Method for the Lateral Pressure in the Gangue-filling Compression Test
Gangue backfilling mining is a new technology in the process of roadway backfilling mining,the lateral pressure of coal pillar caused by gangue expansion has a beneficial effect on strength of coal pillar.The lateral pressure calculation in the roadway backfill mining is deduced,and test of gangue backfilling mining is carried out.Pressure curve of single particle size of gangue and continuous gradation gangue filling test is analyzed,the results show that:compared with the continuous gradation gangue,lateral pressure curve of single particle size of gangue will appear fluctuation phenomena;lateral pressure curve of gangue can use linear function of y =Bx.
