With the increase of mining depth year by year,the problem of roadway heaving floor becomes more and more serious,it affects the coal mine normal and safety production seriously.Aiming at the actual geological con-dition of third level track alleys and the characteristic of serious heaving floor of the roadway in a coal mine,the meth-od which combines field test with theoretical analysis and numerical simulation is adopted,the program that high-strength bolt-net-cable treat heaving floor in deep hole soft rock roadway is put forward,and industrial experiment is conducted,it obtains favourable effect.
