Method for preventing and treating rock burst of mining disturbance type coal roadway by using shear thickening fluid
According to the method for preventing and treating the rock burst of the mining disturbance type coal roadway through the shear thickening fluid, the property that the shear thickening fluid is converted into a hard solid with high resistance after being impacted, and is converted into fluid after the impact disappears is utilized; the method adapts to the low-energy vibration phenomenon and the surrounding rock deformation phenomenon caused by stoping disturbance before the rock burst occurs, resists the rock burst when the rock burst occurs, and avoids the instantaneous coal rock throwing phenomenon after the rock burst occurs, so that effective prevention and control before, during and after the rock burst occurs are realized. According to the scheme, the problems that in the prior art, when rock burst is generated in a stoping disturbance type coal roadway, good rock burst prevention and control performance cannot be still achieved under the influence of a low-energy vibration phenomenon caused by stoping disturbance and surrounding rock deformation, and equipment damage and casualties caused by instantaneous coal rock throwing when the rock burst occurs cannot be effectively avoided are solved.
本发明提供了一种剪切增稠流体防治回采扰动型煤巷冲击地压的方法，本发明的技术方案利用剪切增稠流体受到冲击转变为具有强抵抗力的坚硬固体，而冲击消失后又会转变为流体的性质，实现适应冲击地压发生前回采扰动所致低能量震动现象和围岩变形现象、冲击地压发生时抵抗冲击地压，且在冲击地压发生后避免煤岩瞬时抛出现象的发生，从而实现冲击地压发生前、中、后的有效防治。该方案解决了现有技术回采扰动型煤巷产生冲击地压时，无法在回采扰动所致低能量震动现象和围岩变形影响下仍具备良好防治冲击地压性能，及无法有效避免冲击地压发生时煤岩瞬时抛出造成设备损害、人员伤亡的问题。
