摘　　要：利用黑岱沟露天煤矿的爆破资料,开展黑岱沟煤矿抛掷爆破地方性震级与炸药量的关系的研究。为了避免矿山地震台网地震仪在长期观测中传递函数、归一化因子、放大倍数等参数出现错误,开展同址台站对比分析,实时监控、修订参数。实测结果显示,同址两台站记录到的爆破波形特征非常一致;使用矿山地震台网资料,采用5 km以内的地方性震级M_(L)的量规函数,测定了2023年5-8月4次爆破的地方性震级M_(L);联合使用矿山台网和内蒙古地震台网记录到的44次爆破的数据,采用正交回归方法,得到黑岱沟煤矿抛掷爆破地方性震级M_(L)与炸药量Y之间的经验公式为:M_(L)=3.15lg Y-6.88。Based on the project“Application and Research of Hurling Blasting Vibration Control Technology in the Hedaigou Coal Mine”,we use the blasting data of the Hedaigou Coal mine to study the relationship between the local seismic magnitude(M_(L))and the explosive quantity of the hurling blasting in the Hedaigou Open Pit Coal Mine.In order to address the errors in transfer function,normalization factor,magnification,and other parameters of the seismographs of the Seismic Network of the Hedaigou Coal Mine during long-term observation,we carry out a same-site monitoring of the blasting to do real-time revise of the parameters of the seismographs of the Seismic Network of the Hedaigou Coal Mine.We find that the blasting waveforms recorded by the two seismographs from two different seismic networks at the same site are consistent.Using the near-field data of the Seismic Network of the Hedaigou Coal Mine and the gauge function of the local magnitude(M_(L))within 5 km,we calculate the local magnitudes(M_(L))of four blasts from May to August in 2023.On the basis of the data of 44 blasts recorded by the Seismic Network of the Hedaigou Coal Mine and the Inner Mongolia Seismic Network,and using the orthogonal regression method(OR),we obtain the empirical relation between the local seismic magnitude M_(L)and the explosive quantity Q of the hurling blasting in the Heidaigou Coal Mine:M_(L)=3.15lg Q-6.88.
