Product Introduction

Mechanism and risk assessment of overallinstability

Jun 01 2018 With coal resources being continuously extracted for decades a great number of coal mines in China have entered into deep mining and as a result rockbursts have become one of the most dangerous dynamic hazards1 2 3 4 5 6 To date around 180 rockburst prone mines have been identified with over 50 of them currently mining at a critical depth of over 1000 m7 8 Even worse

Sep 17 2014 Identification and assessment of site specific coal mining risks This part of the report should identify the potential risks associated with coal mining legacy for the proposed development site

the risk of explosion by using the risk index and risk matrix Pejic et al 2013 Jiqiang and Litao performed a comprehensive evaluation of coal mi ne safety based on uncertain random variables

Jun 01 2016 Hazards identification is the basis and premise of risk control management of safety in coal mines There are a host of identification methods Bi and Zhang 2010 such as Preliminary Hazard Analysis PHA Hazard and Operability Study HAZOP Fault Tree Analysis FTA Event Tree Analysis ETA Work Task Analysis WTA Safety Check List SCL and Brainstorming

Safety Measurements and Risk Assessment of Coal Mining

Ljiljana proposed a new risk assessment tool by using a semiquantitative estimation for the risk of explosion by using the risk index and risk matrix Pejic et al 2013 Jiqiang and Litao performed a comprehensive evaluation of coal mine safety based on uncertain random variables and chance measure Chen et al 2014

Human and Ecological Risk Assessment of Coal Combustion Wastes April 2010 DRAFT US Environmental Protection Agency Office of Solid Waste and Emergency Response

A coal burst risk assessment consists of evaluating the degree to which these risk factors are present and then identifying appropriate control measures to mitigate the hazard

Aug 01 2021 Tian 2001 proposed the Theory of Three Types of Hazards which classifies hazards into the following three types of dangerous sources accidental discharge of energy or a dangerous substance unsafe factors eg safety equipment failure individual unsafe behaviour etc that lead to invalid functions that fail to restrict the first type of hazard and institutional mistakes eg culture

Controlling fire and explosion risks WorkSafeqldgovau

Controlling fire and explosion risks Fire and explosion can have catastrophic consequences You must control ignition sources such as naked lights sparks and mobile phones where flammable atmospheres may exist Fire and explosion can result in catastrophic consequences causing serious injuries or death of workers and others as well as

Jan 15 2018 The main purpose of this study is to present a geologicalgeotechnical risk assessment model for identification of high riskprone areas in underground coal mines using an integrated GISgeostatistics system Tabas as the first mechanized and largest underground coal mine in Iran was selected as a case study in this study

Sep 23 2019 Historically coal mining has been a very dangerous activity and the list of historical coal mining disasters is a long one In the US alone more than 100000 coal miners were killed in accidents in the twentieth century 7 most of these fatalities occurring in the first half of the century

Coal plays a vital role in sustainable development The coal is a nonrenewable source of energy including electricity As for nonrenewable resources like fossil fuels their use reduces the stock available within the earth for future generations But this does not

A Cutting Pattern Recognition Method for Shearers Based

In order to guarantee the stable operation of shearers and promote construction of an automatic coal mining working face an online cutting pattern recognition method with high accuracy and speed based on Improved Ensemble Empirical Mode Decomposition IEEMD and Probabilistic Neural Network PNN is proposed An industrial microphone is installed on the shearer and the cutting sound is

quantification of the risk the plant equipment and personnel are exposed to accidents resulting from the hazards present in the plant Risk assessment involves the identification and assessment of risks to the population which is exposed to as a result of hazards present This requires an assessment of failure probability credible accident

Silica exposure is a still a significant risk in many mines in South Africamost notably gold and coal Crystalline silica microscopic in size can scar the lining of the lung As this lining thickens the lungs are less able to extract oxygen from the air and supply it to the blood Susceptibility to other infections such as TB increases

Hazard identification risk assessment and control are considered a successive holistic process placed at the core of risk management in todays business world and requires good planning

Isolate deenergise lockout and tagout plant WorkSafe

The risk assessment will confirm whether plant can be substituted or whether permanently fixed guards an interlocked system or other nonadministrative guarding systems are reasonably practicable methods to remove all sources of energy from the plant to make it safe

14 Proportionality and Depth of Risk Assessment Pro portionality will influence the type and level of analysis detail that Assessors might expect to underpin the various demonstrations in the safety report The following RA definitions are relevant a Qualitative risk assessment is the comprehensive identification and description of

Hazard Identification HAZID is a brainstorming workshop with a multidisciplinary team to identify potential hazards HAZID studies may be broad in their scope and thus have a wide applicability HAZID typically examines all reasonably possible sources of hazard during project design construction installation and decommissioning

NOTE This document may be used as an aid to assist in identification of hazards but should not be solely relied on for that purpose Sources of other relevant information such as that referred to in section 4 of this guideline should be utilised as should details of accidents or dangerous incidents which have occurred with other shearers

23 HAZARD AND RISK

2322 HAZARD IDENTIFICATION AND ASSESSMENT The hazard identification has covered the matters raised in the Terms of Reference together with the results of a systematic process to identify all credible hazards for the Project including the overall Project risk assessment
