Thus the prediction of mining tremor must be studied further. History and current situation of mining tremor was described .The prediction of mining tremor and prevention technology was formulated. The occurrence and formation mechanism of mining tremor was studied and classified. The formulation of P wave and S wave、velocity and motion status were simply demonstrated. Several kinds of interference factors were introduced. On the basis of operation principle about the level putting、vertical putting and other putting, the signal pick-up was introduced and the signal pick-up system was designed. Combination with the geological features of terrain of the ravine mining area of wooden city in Beijing, a set of slight shock automatic recognition system was designed. The composition of monitoring decorating and platform of the network was analyzed. In the end the designed system was debugged. The microseism signal automatic recognition system can pick up and analysis P wave 、S wave and the interfering signal in the microseism signal caused by the mining tremor, determine the time of signal arrival and amplitude, energy etc. And this will offer the essential parameter for predicting and preventing the calamity of mining tremor.
