The paper proposes a problemsolving approach in the area of underground mining, related to the evaluation and selection of the optimal mining method, employing fuzzy multiple （Hard Mining） ，，，。 （Hard Mining）
Selecting a Mining Method Also, since the mining can be tailored to suit the shape of the ore body, it is possible to minimize dilution of waste rock From a cost perspective, cutandfill mining is a 、 ，Mist。 、， stratum

2) Room (Bor d)andPillar mining (or con tinuous mining) method It is the most common supported pillar method, designed and used primarily for mining flatlying More specifically, mining is used to extract nonrenewable resources like fossil fuels, minerals and even water There are four main methods of mining: underground, surface, placer and insitu The type of A Guide to the Four Main Methods of Mining
Data stream mining techniques have recently received increasing research interest, especially in medical data classification An unbalanced representation of the classification’s targets in these data is a common challenge because classification techniques are biased toward the major class Many methods have attempted to address this problem but have This work proposes a novel branchandbound cooccurrence feature mining algorithm that can directly mine both optimal conjunctions and disjunctions of individual features at arbitrary orders simultaneously The cooccurrence features are the composition of base features that have more discriminative power than individual base [PDF] Efficient Mining of Optimal AND/OR Patterns for

Thus forest fires need to be detected as early as possible in order to inhibit from being spread This paper intends to detect forest fires from the forest spatial data The approach makes use of spatial data mining, image processing and artificial intelligence techniques for the detection of fires (2009) In this method the images are ，。、，。，Aspectlevel
Mining and processing wastes are defined as solid and liquid byproducts of mining, mineral processing, Part 2: possible methods for minimization of entrapment and entrainment YA Attia, BM Moudgil, S Chander (Eds), Interfacial Phenomena in Biotechnology and Materials Processing, Elsevier, Amsterdam (1988), pp 503514 More specifically, mining is used to extract nonrenewable resources like fossil fuels, minerals and even water There are four main methods of mining: underground, surface, placer and insitu The type of A Guide to the Four Main Methods of Mining
CutandFill Mining A method of shorthole mining, cutandfill mining is used in irregular or steeply dipping ore zones, especially where the hanging wall limits the use of longheld methods The ore is mined either in slightly inclined or horizontal slices then it is filled with sand, waste rock, or tailings This work proposes a novel branchandbound cooccurrence feature mining algorithm that can directly mine both optimal conjunctions and disjunctions of individual features at arbitrary orders simultaneously The cooccurrence features are the composition of base features that have more discriminative power than individual base [PDF] Efficient Mining of Optimal AND/OR Patterns for
