“…geographical proximity to both a strong particle physics laboratory and a strong volcanology institute. This is often the case in countries where both communities are well developed, explaining the number of activities in Japan [31], Italy [32], and France [16,33]. Static pictures using muon data integrated over several months can be used to investigate the inner composition of a volcano providing information on the location of volumes of rocks with different densities, that is essential to the understanding of the volcano's history.…”

Imaging methods based on the absorption or scattering of atmospheric muons, collectively named under the neologism "muography", exploit the abundant natural flux of muons produced from cosmic-ray interactions in the atmosphere. Recent years have seen a steep rise in the development of muography methods in a variety of innovative multidisciplinary approaches to study the interior of natural or man-made structures, establishing synergies between usually disconnected academic disciplines such as particle physics, geology, and archaeology. Muography also bears promise of immediate societal impact through geotechnical investigations, nuclear waste surveys, homeland security, and natural hazard monitoring. Our aim is to provide an introduction to this vibrant research area, starting from the physical principles at the basis of the methods and reviewing several recent developments in the application of muography methods to specific use cases, without any pretence of exhaustiveness. We then describe the main detector technologies and imaging methods, including their combination with conventional techniques from other disciplines, where appropriate. Finally, we discuss critically some outstanding issues that affect a broad variety of applications, and the current state of the art in addressing them. a

“…(2) Muon Detectors There are currently three main types of detectors used for muography applications: mobile radiography detectors, static tomography detectors and borehole detectors (see e.g., Fig. 3 in Marteau et al 2015, andFigs. 5, 6 in Kaiser 2019).…”

“…Up till now muography has been applied to or tested in many fields. For example, muography has been used in the imaging of volcanoes (Nagamine et al 1995;Tanaka et al 2007Tanaka et al , 2009Tanaka et al , 2014Okubo and Tanaka 2012;Lesparre et al 2012;Marteau et al 2012Marteau et al , 2015Shinohara and Tanaka 2012;Carlôganu et al 2013;Tanaka and Yokoyama 2013;Nishiyama et al 2014;Ambrosino et al 2015b;Jourde et al 2016;Tioukov et al 2017;Noli et al 2017;Kaiser 2019;D'Alessandro et al 2019;Oláh et al 2019;Tanaka 2019;Barnoud et al 2019;Lelièvre et al 2019), in mining exploration (Schouten 2019), in the imaging of underground structures (Bonneville et al 2019;Saracino et al 2019), in archaeology and tunnel detection (Basset et al 2006;Menichelli et al 2007;Levy et al 1988;Celmins 1990;Caffau et al1997;Morishima et al 2017), in the monitoring of carbon capture storage sites (Kudryavtsev et al 2012;Jiang et al 2013;Klinger et al 2015;Gluyas et al 2019), in scanning old mining sites to detect the possible presence of unknown cavities (Baccani et al 2019;Mitrica et al 2019), in investigation of mineral deposits and rock density measurements…”

Muography is a novel imaging method using natural cosmic-ray radiation for characterising and monitoring variation in average material density in a diverse range of objects that cannot be imaged by conventional imaging techniques. Muography includes muon radiography and muon tomography. Cosmic-ray-induced muons were discovered in the 1930’s, but rapid development of both muographic techniques has only occurred in the last two decades. With this rapid development, muography has been applied or tested in many fields such as volcano imaging, archaeology, underground structure and tunnel detection, rock mass density measurements, cargo scanning, imaging of nuclear waste and reactors, and monitoring of historical buildings and the inside of blast furnaces. Although applications of muography have already touched mining and rock engineering, such applications are still rare and they are just beginning to enter the market. Based on this background, this paper aims to introduce muography into the fields of mining and rock engineering. First, the basic properties of muons are summarized briefly. Second, potential applications of muography to mining and rock engineering are described. These applications include (1) monitoring temporal changes in the average material density of fracturing and deforming rock mass; (2) detecting geological structures and isolated ore bodies or weak zones in mines; (3) detecting a reservoir or boulders during tunnelling or drifting; (4) monitoring caving bodies to search remaining ore; (5) evaluating and classifying rock masses; (6) exploring new mineral deposits in operating underground mines and their surrounding brownfields. Finally, some issues such as maximum depth muons can reach are discussed.

“…Recently, Morishima et al (2017) Besides these applications, which have mainly been designed for archaeological and civil engineering purposes, scientists have begun to deploy particle detectors to investigate and map geological structures. In recent years this has been done for various volcanoes in Japan (Nishiyama et al, 2014;Tanaka et al, 2005Tanaka et al, , 2014, in the Caribbean and in France (Ambrosino et al, 2015;Jourde et al, 2013Jourde et al, , 2015Lesparre et al, 2012;Marteau et al, 2015). Recently, Barnaföldi et al (2012) used this technology to examine karstic caves in the Hungarian mountains.…”

Abstract.In recent years, the use of radiographic inspection with cosmic-ray muons has spread into multiple research and 10 industrial fields. This technique is based on the high-penetration power of cosmogenic muons. Specifically, it allows the resolution of internal density structures of large scale, geological objects through precise measurement of the muon absorption rate. So far in many previous works, this muon absorption rate has been considered to depend solely on the density of traversed material (under the assumption of a standard rock) but the variation in chemical composition has not been taken seriously into account. However, from our experience with muon tomography in Alpine environments we find 15 that this assumption causes a substantial bias on the muon flux calculation, particularly where the target consists of high { 2 ⁄ } (like basalts) or low { 2 ⁄ } (e.g. dolomites) rocks and where the material thickness exceeds 300 metres. In this paper we derive an energy loss equation for different minerals and we additionally derive a related equation for mineral assemblages that can be used for any rock type on which mineralogical data is available. Thus, for muon tomography experiments in which high/low { 2 ⁄ } rock thicknesses can be expected, it is advisable to plan an accompanying geological 20 field campaign to determine a realistic rock model.
