"Simulating Test Instruments for Revealing the Mechanism and Law of Coal and Gas Outburst" The annual progress seminar initiated by CUMT, with Huainai Mining Group and Shandong University as co-participants, was led by Professor Yuan Liang from Anhui University of Science and Technology. The project is sponsored by National Natural Science Foundation of China.

The seminar reported on the following:

ü The coal and gas outburst simulating test is a worldwide difficulty

ü The project is in line with China’s major demands

ü The preliminary research work has been smooth and great progress has been made in many aspects such as basic theories and simulation experiments

ü This project has also provided advice on the apparatus sealing scheme, the selection of materials, the reliability of the data, the repeatability of the experiment and the scale effect

ü The project team would elaborate on the research plan, and promptly publish research results to promote the project to the world at an advanced level.

It was further reported that the national significant instruments research and development project aims at:

ü Developing the simulating test instruments which can be used to reveal the mechanism and law of coal and gas outburst

ü Achieving the international leading instrument performance indicators

ü Overcoming the world-wide problems of mechanism and outstanding laws in coal and gas outburst.

This project is also committed to:

v Building significant scientific instruments and creating a public researching platform with independent intellectual property rights of studying the mechanism and law of coal and gas outburst

v Providing scientific support for prediction and prevention of coal and gas outbursts in deep and high-gas mines

Since the project was approved in October 2014, significant breakthroughs have been made in seven aspects including:

Ø key unit development

Ø similarity criteria derivation

Ø similar materials compounding ratio

Ø high-frequency sensor development

Ø high-speed multi-parameter information acquisition and

Ø constant-capacity experiments.

Academician Yuan Liang, the project leader, introduced the basic situation and research value of the project. After Professor Wang Hanpeng's report, Academician Yuan Liang pointed out that the overall progress has been made smoothly since the implementation of the project. Experts at the mid-term examination report in April this year gave high praises and recognition to the results of the project, and also put forward some pertinent opinions. The three parties are expected to work closely together and to focus on the collaborative innovation and mutual support with the national key R&D plan "Researches on Risk identification and Monitoring and Early Warning Technology for Typical Dynamic Disaster of Coal Mining" undertaken by Anhui University of Science and Technology.
