四棵杨树矿床开发建设爆破危害探讨

Discussion on Blasting Hazards of Development and Construction of Sikeyangshu Mine

考虑到爆破地震对地表村庄和村民的影响,分析了四棵杨树矿床在开发建设过程中爆破地震波产生的危害,采用质点峰值振动速度来探讨矿床开采爆破地震对地表村庄的影响,采用地震烈度的评价方法来进行验证,在此基础上提出了防治开发建设爆破作业危害的措施。结果表明,四棵杨树矿床开发建设爆破地震危害较小,爆破作业是安全的。

The influence of blasting vibration to village and villagers in the surface in the process of development and construction of Sikeyangshu mine should be considered. So, the harms of seismic wave is analyzed, the peak particle Vibration velocity method is adopted to analyze the influence of mining blas- ting vibration to village in the surface, the earthquake intensity is used to verify the above analysis re- suits. Besides that, the measures of prevention and control of blasting operation of development and con- struction are proposed. The research results indicated that, the blasting struction of Sikeyangshu mine is less harmful to village and villagers in blasting operation is safe. vibration of development and con- the surface, therefore, the mining
