Prevention and treatment method for water and mud bursting disasters of working face

The invention discloses a prevention and treatment method for water and mud bursting disasters of a working face. The method comprises steps that before the working face with the water-bursting and mud-bursting disasters under the preset geological condition is stoped, a water-rich area of a roof aquifer is detected, and the detection vertical depth is larger than the development height of a mining-induced water flowing fissure zone; according to the detected area, roof drilling is constructed to conduct drainage on the water-rich area of the main aquifer. In the drilling construction process, abnormal conditions such as drill jamming and hole collapse are recorded, coring is conducted on a rock stratum in a caving zone, lithologic characteristics are recorded, and the vertical distance between thick-layer mudstone and a working face top plate is judged. In stoping, directional drill holes are constructed in two gate roads near a working face, the final hole position of each drill hole is located within 6 m a
