摘要

PT. PAMA是一家从事采矿的公司，是PT. Indominco Mandiri的承包商，自1996年以来一直在运营。该工程合同是爆破，爆破活动产生了许多影响，其中之一是地面振动，因此有必要测量西部区块区域的地面振动水平，该区域有几个关键区域，如办公室、太阳能(燃料油)储存和Indominco Mandiri PT，那里有关于大振动和燃料油泄漏柴油的可能性的投诉。研究中，2022年12月产生的峰值矢量和(pv)值为1.57 mm/s，最近距离为785 m, 2023年1月产生的峰值矢量和(pv)值为4.21 mm/s，距离为500 m。2022年12月和2023年1月爆孔最大炸药用量2513公斤。这个pv值仍然是安全的，因为它仍然低于5.0 mm/s，并且根据SNI 7572: 2010。

Studi Studi Pengaruh Tingkat Getaran Tanah (Ground Vibration) Akibat Peledakan Terhadap Bangunan sekitar Pit 13 HW

PT. PAMA is a company engaged in mining and is a contractor of PT. Indominco Mandiri which has been running since 1996. The work contract given is blasting, from blasting activities many impacts arise, one of which is ground vibration, therefore it is necessary to measure the level of ground vibration in the west block area where there are several critical areas in the form of buildings such as offices , solar (fuel oil) storage, and PT. Indominco Mandiri, where there have been complaints regarding large vibrations and the potential for diesel spills from fuel oil. In the study the peak vector sum (pvs) value produced in December 2022 was 1.57 mm/s with the closest distance of 785 meters and in January 2023 4.21 mm/s with a distance of 500 meters. The maximum use of explosives item for explosive holes in December 2022 and January 2023 is 2,513 kg. This pvs value is still safe, because it is still below 5.0 mm/s and according to SNI 7572: 2010.

期刊介绍： Mineral Economics – Raw Materials Report is an international multidisciplinary journal focused on economics and policy issues in the minerals metals and mining industries. The journal exists to improve the understanding of economic social environmental and political implications of natural resources. The main focus is on non-fuel minerals metals and the mining industry and its role in society.Mineral Economics is widening its scope and particularly invites papers on: Socio-economic aspects of mining e.g. social license to operate indigenous peoples theory of change Materials for the Green transition e.g. battery metals ICT elements policies to secure supply of these elements Minerals in the periphery e.g. the Arctic deep-seabed and space Mineral Economics serves as a platform for academics industry practitioners decision makers and other experts who want to share perspectives and knowledge about natural resources.A wide range of topics have traditionally been covered including among others: mineral market analysis exploration and development resource availability market development price formation international trade environmental policy sustainability issues competition issues.Mineral Economics is a joint project of Lule? University of Technology and R?varugruppen Ekonomisk F?rening the organization which founded the journal Raw Materials Report in 1981
