Deep soft rock tunnel supporting was currently one of the mine pressure boundary support problem. According to the field of engineering practice， through reasonable and effective support scheme design， the supporting parameters of roadway were optimized. Grouting bolt and grouting anchor cable anchor combined support roadway two sides injection technology was adopted， with baseboard inverted arch and timely monitoring of the mine pressure. The result showed that grouting bolt and anchor cable got good effect in deep soft rock tunnel surrounding rock control， roadway inverted arch could effectively control deep roadway floor heave.
