The invention relates to a rock burst predicting and warning method, which effectively and accurately predicts and warns the rock burst and ensures safety in coal production. The rock burst predicting and warning method comprises the following steps of: performing shock bump monitor on a whole coal field, determining the magnitude, and analyzing generation and motion law of the shock bump in the whole coal field; mounting a Poland micro-quake system on upward and downward roads and a main haulageway in the mining area to perform on-line continuous monitor; mounting a micro-quake system probe on a working surface, mounting a micro-quake monitor probe in an important anti-scour area of the working surface to perform overall arrangement, drilling a coal wall or a top plate, placing the probe in the hole bottom and the hole wall, perform electromagnetic radiation monitor on a tailentry and the main haulageway by using an electromagnetic radiometer to, arranging a monitor probe in the important anti-scour area to perform overall arrangement, monitoring the coal pressure, and inputting the monitored parameters into a computer to perform comprehensive analysis, so as to accurately predict the rock burst. Various items of monitor are integrated together, the predicting and warning accuracy is increased, and the rock burst predicting and warning method provides the technical support for eliminating the rock burst condition and reducing the loss due to rock burst.
