Induced hydraulic fractures in underground block caving mines
Block caving is an underground rock mining method primarily based on the principle of sequential caving operations. The block caving method assumes that The term ‘cave mining’ is used in these guidelines to include non-selective mass underground mining methods that harness the energy generated by gravity and induced stresses in order to break New to our Series!

Block Caving: A Viable Alternative? WSP
Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight and Among underground mining methods, block caving is the most cost-effective as it can produce 10,000–100,000 tons per day with a relative operating cost of USD 1 to 2.5 per ton [6,7].

Cave Mining Techniques
The difference between panel cave mining and block cave mining is attributed to the production process that moves sequentially along the length of the orebody so that only when one section of the ore is in production is the next one blasted. Underground Mining Methods: Engineering Fundamentals and International Case Studies (SME, 2001)In Chile, the block caving method is commonly used in massive underground deposits where less development is required. Here, the cave is naturally filled with broken material and a large subsidence zone is generated. In this review, it has been observed that different underground methods and strategies can be effectively used in Energies Free Full-Text Review of Underground Mining Methods

Major Mines & Projects Padcal Mine
Summary: Operating at the Padcal mine using the underground block cave mining method. Load-Haul-Dump (LHD) mining is a system of ore extraction in block caving using the Low Profile Loaders. It was introduced at 908 ML on May 1996 after a series of consultation with block caving experts and by 1999, Philex became a full LHD block Cave mining has spread over the last 20 years due to the depletion of shallow ore bodies (typically mined via open pits) and the drive for the high underground production rates and low operating costs that cave mining offers. This method also suits scenarios where ore continues below final open pit bottoms. Because caving techniques can be usedCave Mining Consultants Mining Engineering SRK

Study of the Influence of Block Caving Underground Mining on
Among the underground mining methods, block caving mining is a viable and preferred method for the extraction of low-grade orebody due to its low cost and high production rate. (2013) Empirical investigation and characterization of surface subsidence related to block cave mining. Int J Rock Mech Min Sci 61:31–42.Block caving is regarded as one of the most productive and lowest cost underground mining methods and as such is often applied to low grade ore bodies. The method uses gravity force in conjunction with internal rock stress which leads to fracturing of the rocks and eventually breaks them into small enough pieces which can be extracted Mining Methods SpringerLink

Raise Caving—A Hybrid Mining Method Addressing Current Deep Cave
Cave mining progresses to depths exceeding 1000 m and ore bodies situated in competent and strong rock masses are nowadays extracted by different cave mining methods. Widely applied caving methods in massive deposits are block and panel caving, inclined caving, and sublevel caving. All caving methods have in common that This paper presents measurements and analyses of LoRa propagation in an underground block cave gold mine in New South Wales, Australia. LoRa is an important technology for the Internet of Things with considerable potential for underground mining.
