METHOD FOR ROCK BURST PREVENTION BY ACTIVE SUPPORT REINFORCEMENT AND ACTIVE PRESSURE RELIEF

China University of Minin...

1. A method for rock burst prevention by active support reinforcement and active pressure relief, specifically comprising the following steps:A) Rating a burst tendency based on a comprehensive index method:
rating is performed by using a comprehensive index method according to a rock burst risk status as well as degrees of influence on a rock burst from geological factors around a mining face in danger of bursts and mining technique factors; if a burst risk index of a region is less than 0.25, it is defined as a risk-free region, and stoping is performed normally in this case without the need for pressure relief; if the burst risk index is 0.25 to 0.5, the region is defined as a general risk region; if the burst risk index is 0.5 to 0.75, the region is defined as a mediate risk region; if the burst risk index is greater than 0.75, the region is defined as a high burst risk region, and stoping is stopped in this case;
B) Predicting and monitoring a burst risk level of a burst risk region and determining pressure relief borehole parameters by using a drill cuttings method:
20 holes with a diameter of 42 mm, a depth of 6 to 8 m and a pitch of 3 to 5 m are drilled in a normal-pressure coal seam on the external side of the working face, the boreholes being parallel to an inclination direction of the coal seam and having a height of 1.0 to 1.2 m to the floor; the amount of pulverized coal per meter of each hole is recorded; then a weighted average of the recorded amounts is calculated as a standard amount of pulverized coal, a curve of the standard amount of pulverized coal is drawn, and a peak value of the amount of pulverized coal is marked; next, boreholes are drilled at intervals of 3 to 5 m from a coal wall of the working face towards two sides of the external roadway, and the amount of pulverized coal per meter of each hole is recorded; then the recorded amount is compared with the standard amount of pulverized coal to calculate a difference; if the difference is greater than twice a normal value, it indicates that the region already has a burst risk;
if the burst risk region is rated as the general risk region in step A), the pressure relief borehole parameters are as follows: the borehole depth is not less than 10 m, the borehole diameter is not less than 110 mm, and the hole pitch is 4 m; and
if the burst risk region is rated as the mediate risk region in step A), the pressure relief borehole parameters are as follows: the borehole depth is not less than 15 m, the borehole diameter is not less than 110 mm, and the hole pitch is 3 m;
C) Drilling holes after determining arrangement patterns of large-diameter pressure relief boreholes according to different burst risk levels:
if the burst risk region is the general risk region, the arrangement pattern of pressure relief boreholes is as follows: in an area covering above 50 m behind the excavation heading or in the burst risk region, large-diameter boreholes with a hole diameter greater than 110 mm and a hole depth of 10 m are drilled at intervals of 2 to 3 m, the boreholes being perpendicular to the integrated coal and arranged in a single row along the center line of the roadway; two large-diameter boreholes with a hole depth of 10 m are arranged at the heading; and
if the burst risk region is the mediate risk region, the arrangement pattern of pressure relief boreholes is as follows: in an area covering above 50 m behind the excavation heading or in the burst risk region, large-diameter boreholes with a hole diameter greater than 110 mm and a hole depth of 20 m are drilled at intervals of 1.5 m, the boreholes being perpendicular to the integrated coal and arranged in a staggered pattern, with a distance of 0.8 to 1.5 m to the floor; two large-diameter boreholes with a hole depth of 20 m are arranged at the heading;
D) Forming a coal wall-bolt-grouting hole sealing support reinforcement system through a roadway support system:
Hollow grouting bolts are installed in the large-diameter pressure relief boreholes on two sides of the roadway, a bolt length being slightly greater than a hole sealing length; then grouting hole sealing reinforcement is performed, the hole sealing length being set to 10 m or 5 m; because the integrity of the coal wall is maintained after grouting reinforcement while the coal wall near the boreholes is hardened due to the effect of grout, the coal wall-bolt-grouting hole sealing support reinforcement system is formed; and
E) Monitoring a pressure relief effect of the support reinforcement system:
rock bursts are monitored through multiple drill cuttings measuring points arranged in step B); if the pressure relief effect of the support reinforcement system does not achieve an effect of lowering the level of the burst risk region, step C) is performed again to further increase the drilling density, thus ensuring the pressure relief effect of the pressure relief boreholes; after the interior of each pressure relief borehole is adequately broken up, the drill cuttings method in step B) is further performed at the intact coal wall near the pressure relief borehole to monitor rock bursts; if the effect of lowering the level of the burst risk region is still not achieved, steps C) and D) are repeated to drill holes and perform the grouting hole sealing method again, until the required effect of preventing bursts by pressure relief is achieved while the performance of support reinforcement is achieved.
