Bài viết sử dụng các kết quả đo giám sát nổ mìn tại mỏ đá vôi Ninh Dân, huyện Thanh Ba, tỉnh Phú Thọ và sử dụng các mô hình khác nhau để dự báo tốc độ dao động của nền công trình ảnh hưởng đến các công trình bảo vệ xung quanh. | 102 Journal of Mining and Earth Sciences Vol. 61 Issue 4 2020 102 - 109 Prediction of the peak velocity of blasting vibration based on various models at Ninh Dan quarry Thanh Ba district Phu Tho province An Dinh Nguyen 1 Hieu Quang Tran 1 Bao Dinh Tran 1 Phonepaserth Soukhanouvong 2 1 Faculty of Mining Hanoi University of Mining and Geology Vietnam 2 PhD Candidate Surface Mining Department Hanoi University of Mining and Geology Vietnam ARTICLE INFO ABSTRACT Article history In mining industry blasting operation is effective method to fragment Received 05th Apr. 2020 rocks supporting for the next operations in surface mines such as loading Accepted 13rd July 2020 and hauling works. However blasting operation also impacts adversely Available online 31st Aug. 2020 on buildings and the surrounding environment in which the vibration Keywords wave is one of the most severe impacts. Therefore the implementation of Blasting the forecasting models of vibration speed contributes significantly to Ground vibration guarantee the safety of buildings located within the impact areas of the vibration wave. This paper employs the monitoring results of blasting Ninh Dan quarry activity at the Ninh Dan limestone quarry situated in Thanh Ba district Peak particle velocity. Phu Tho province to develop different forecasting models that determine the effects of the ground vibration speed in the surrounding buildings. The results show that the models USBM and Ambraseys Hendron having more accuvate prediction than other models. Copyright 2020 Hanoi University of Mining and Geology.
