Introduction
The project report is discussed about important of ventilation safety, legislation and regulation essential for mining underground safety. The project aim is to evaluate and become familiar with the current government regulation as Australian government regulation is not equal and same for each state. That means, it varies from one state to another. The project report is discussed about the main elements of the safety regulation that applied for ventilation of coal and non-coal mines for the specific state within Australia. In this report, there is discussion about coal mining, health and safety regulation.
Ventilation aim:
The ventilation is essential an importance aspect for the underground mine and importance to work-related health and safety for the underground worker, engineer, officer and project manager Jong, E.C.et.al.(2016). The natural condition is different in underground coal and non-coal mine. The atmosphere underground is limited and restricted, and that may be dangerous for the worker and employees. In case, uncontrollable condition produces gases, dusts and fumes in the course of operations are not able to control. In this case, the ventilation is used to remove and dilute contaminants.
Objectives
The objective of the coal mining safety and health regulation declared in 2019 is specified and improved version of requirement of underground coal mines. In specific, in the relation to the automatic methane detectors in the return airways which intersect with the long-wall face. Further, the legislation established as the legislative framework with the specific objectives of protecting the health and safety of the worker at the coal mines and employees those get injured in the coal mines operations, essential particular risk of injury or illness to the specific person resulting from coal mining and admin of provision concern to the safety and heal under the define act.
The legislation establish the framework with the specific objectives to prevent the safety and coal mining safety and health regulation as per 2017 which supports the operation of the act by prescribing way of protecting the health and safety employees at the coal mines and achieve specific level of the risk in specific circumstances which depiction workers to the risks at the coal mines.
The Regulation specifies where methane monitors must be located and how methane levels in underground coal mines must be monitored and risk managed to ensure operations are at an acceptable level of risk. ‘
Compliance audits by the Coal Mines Inspectorate within the Department of Natural Resources, Mines and Energy (DNRME) and analysis of real time gas monitoring data from underground coal mines have shown there is a need to update and clarify some sections of the Regulation. In particular to ensure that dangerous explosive levels of methane are not accumulating in the longwall tailgate return roadway, during operation of the long-wall equipment at the longwall face.
Improved methane monitoring in longwall return airways is required. As Queensland’s underground coal mines have become deeper and production rates have increased over recent years, the concentration of methane detected in longwall return airways has been increasing, in the majority of underground coal mines Jacobs, W. et.al.(2014).
Under the Act and the Regulation, if methane concentration is equal to or greater than 2.5 per cent, then the underground coal mine or part of the mine is dangerous and coal mine workers must be withdrawn from the mine, or the part of the mine that is dangerous. Such an event is a high potential incident and the site senior executive must notify an inspector from Coal Mines Inspectorate, as soon as practicable after becoming aware of the incident. Ventilation is explosive between 5 per cent and 15 per cent Kamyar, A.et.al.(2016).
Additionally, the compliance audits at the underground coal mine demonstrate that there are some mines which have not been time after time reporting occurrence of excess methane more than 2.5%. In fact, the coal mines inspection has declare commands to essential underground coal mines to suitable place to fine methane detectors which will not allowing long-well machinery operating. That should methane concentrations increase which not acceptable level in the long-wall tailgate returns roadways.
Why ventilation is important for underground workplaces.
During mining procedure, the gases and dusts are naturally occur, subsequently, the combustion of products, vehicles fumes exhaust emissions and blasting activities usually perform during mining process. During excavation and digging process, the mining activity includes various gaseous elements such as methane, carbon monoxide, sulphur dioxide, ammonia and radon.
In this case, the Methane and other hydrocarbons come across and found during the drilling activity which is considerable high risk and potential explosive. Further, the blast fumes have considerable large number of oxides of nitrogen and carbon monoxide. For that, it is require sufficient ventilation in order to remove contaminants and allows performing air testing before the employees leave their position, place and working condition. the basic and most common mining activity occur of impulsive fusion are within the coal mines. In this situation, due to high flame combustion of sulphide ores is able to produce large amount of sulphur dioxide and carbon monoxide Karacan, C.Ö.et.al.(2011). Further, there is fires occur due to vehicle and other element which contain significant amount of fumes.
The ammonium nitrate fuel oil explosive is effective oxidizing agents and spills of ANFO prill that can invite fire in the contact with the combustibles. Further, the ammonium nitrate, the fuel oil explosive is the powerful oxidizing cause and spills of ANFO prill can manage the fire in contact with the combustion (Holmes, R.I., 2016).
New legislation and statutory position of the ventilation employees based on Queensland state:
a. Each mines whether coal and non-coal, where more than 20 employees work underground must require ventilation officer who has regular meeting arrangement with the Queensland Mining safety and health advisory committees.
b. The officer is responsible for the establish ventilation system and ensure that the ventilation must effective for the mine. The area and mine segment must sustainable and responsible as appoint ventilation officer.
c. In many coal mines in the Queensland and New south Wales, there was found some issues regarding appoint ventilation officer due to high qualified person require and that was difficult for management to appoint regarding to the legal and working position. For example, the ventilation officer must report to the technical service management those have sufficient experience, knowledge and understanding of mine ventilation.
d. In case, the ventilation office is absent from his duty more than 14 days, it is essential to appoint another ventilation officer which require meeting the same profile, profession and capability standards, and require appointing for that position. It is essential that the alternative officer must have sufficient knowledge, experience and qualification in mining area Limbri, H.et.al.(2013).
e. Subsequently, the ventilation officer is absent for less than fourteen days, the underground mining project manager consider that the ventilation officer is available and effectively work as per define duties, position, roles and responsibility for project manager.
f. It is notice that the ventilation officer can’t be appointed as the ventilation officer more than one mine without urgency and pick demand of chief inspector.
g. The project manager and ventilation officer ensure and inform that there are three years transition period for the mines to comply with these new supplies.
In fact, there are developing concern by considering long term health consequences for the underground mine worker in terms of airborne contaminants (Hill, R.L., 2009). There are considerable large range of factors which needs to cover and following is provides some of important elements and concern regarding to the safety and health aspects.
a. In this case, the diesel particulate matter can discussed as the well-known human carcinogen, a specific concern provided the heavy dependences of the diesel machine in the underground metalliferous mining.
b. Further, the international agency for the research on the cancer was conducted research and study of mine’s worker that found that the older engine techniques have considerable high amount of sulphur fuels occur. The old engine produce more toxic elements and harmful for the human body. That will invite cancer and other major disease as well.
The Queensland legislation for mining operation and project highlight four major issues observes that the routine and regular training require for ventilation officers in the Queensland and it is applicable for Australia as well(Patterson, J., 2009).
a. According to legislation, it is essential to enhance the experience, knowledge,...
