Reliable gas monitoring is a key element to ensure that the mine based controls are effective.
Coal mines in Queensland and New South Wales have been facing issues in controlling tailgate methane levels and recently there have been two serious spontaneous combustion events. Legislation and Australian standards make specific requirements for the installation and maintenance of gas monitoring systems.
This paper discusses the issues related to gas monitoring, tailgate methane control, alarm set points and proposals for feedback loops on alarm notifications and acknowledgements. The paper will not discuss individual mine events but will focus on reliable gas monitoring to enable early detection and proactive actions to be taken.

ABSTRACT
There have been many mine disasters in the last century, globally. The common issues faced by mine rescue teams is re-entering the mine to rescue or recover. This paper will focus on actions and risks associated to decisions made during a past major mine disaster in south Serbia, in a small mining community in Aleksinac.
The mine was opened by Djordje Dimitrijevic and Johan Apel on 28th May 1883, for coal to supply Aleksinac Brewery. The first accident occurred in 1924, where 10 miners died. The second accident was in 1983, where 34 lives were lost. The entire north sector morning shift of 90 coal miners were lost at 11:59am on Friday 17th November 1989. The cause of this disaster can be attributed to a negligence and a fire which ignited coal dust in the “Morava” shaft panel number 445, 700m below the surface. The rescue teams risked their lives to recover the bodies of the victims to the surface in 25 days. They entered with minimal knowledge of the underground atmosphere and conditions.
The disaster influenced the decision to close the mine in 1990 despite the 27 million tonnes available coal reserves. On this pleasant and sunny day, 90 families lost their beloved and 132 kids were left without fathers. “We, miners, have a nice greeting “Srećno” (Good luck), and yet we have no luck” stated the late deputy Vukoje Marković, just few days before he lost his life in this terrible mine disaster.

Since the re-identification of coal workers’ pneumoconiosis in Queensland in 2015, and reforms resultant from the Monash and UIC independent expert review of 2016, the department has implemented improved screening methods for the detection of respiratory disease in coal mine workers.
As at March 2019, more than 30,000 chest x-rays have been dual read to International Labour Organisation (ILO) standards, resulting in 99% returning a negative result for disease. Of the 1.0% which screened positive, 15 have resulted in a diagnosis of disease.</p .
The department receives reports of cases of mine dust lung disease (MDLD) through a number of pathways; doctors, mine operators and the workers’ compensation scheme all provide confirmation of diagnoses within the mining and quarrying sectors. As at March 2019, 99 cases of MDLD have been reported across all sectors since 1984 (89 since 2015).
Separate to the reforms implemented in the mining regulatory framework, the Queensland Parliament is considering a Bill to establish a Notifiable Dust Lung Diseases Register to be administered by Queensland Health. This will provide a further mechanism to ensure the incidence of disease is understood.
This paper provides an overview of the current screening pathways to detect MDLD in Queensland mine workers.
