Проблема обеспечения безопасности объектов, которые попадают в зону ведения взрывных работ, обеспечивающих разрушение крепких горных пород, остается актуальной. В статье приводятся результаты крупномасштабного эксперимента по определению безопасных условий ведения буровзрывных работ вблизи действующего газопровода. Наиболее простым и надежным способом обеспечения безопасности охраняемого объекта от сейсмического воздействия является уменьшение интенсивности сейсмовзрывной волны, что достигается путем изменения параметров буровзрывных работ. Для этого необходимы исследования по определению влияния взрывных работ на параметры сейсмовзрывных волн и разработка методик измерения этих параметров. В работе выполнен детальный анализ влияния сейсмовзрывной волны на смещения грунта и модельного газопровода. Показаны особенности проведения сейсмического мониторинга при ведении взрывных работ рядом с действующим газопроводом. Определены коэффициенты сейсмичности и затухания сейсмовзрывных волн. Доказано, что показания сейсмоприемников на поверхности и в глубине массива отличаются в два и более раз.

The problem to ensure the safety of objects which are in the area of blasting operations, ensuring the destruction of hard rocks, remains relevant. The article presents the results of a large-scale experiment to determine the safe conditions for conducting drilling and blasting operations near the active gas pipeline. The simplest and most reliable way to ensure the safety of the protected object from seismic impact is to reduce the intensity of the seismic wave, which is achieved by changing the parameters of drilling and blasting operations. This requires research to determine the impact of blasting operations on the parameters of seismic waves and the development of methods for measuring these parameters. The paper presents a detailed analysis of the seismic blast wave impact on the displacement of the ground and the model gas pipeline. The features of seismic monitoring during blasting operations near the active gas pipeline are shown. The seismic coefficients and attenuation coefficient of seismic waves are determined. It is proved that the readings of the seismic receivers on the surface and in the depth of the massive differ by two or more times.
