Special Issue Information
Dear Colleagues,
With the developments in the past two decades, polymers have been successfully utilized in the underground coal mining industry in a variety of engineering applications, including as anchoring agents, and in grouting, sealing, filling, surface protection, and so on. Deep underground coal mining is faced with deteriorating geological conditions, and polymers show promising prospects to ameliorate these. In particular, the decline in crude oil prices promotes engineering applications using massive polymers. However, the environment of the underground coal mine is harsh, including elements of dust, high temperatures, gas, water, spontaneous combustion, and corrosive chemicals. Moreover, the underground space is narrow, tight, semi-hermetic, and limited in power. High ground stress and mining-induced disturbances can also cause large deformations of surrounding rock structures and even ground control failure. Therefore, the polymer materials, equipment, and technologies used in ground engineering need to be modified according to the geological environments in different underground coal mines. Polymer applications without adequate engineering experience can cause serious accidents.
This Special Issue plans to summarize the recent advances in the application of polymers in underground coal mines. New polymer materials, equipment, and technologies with sound application potential in deep underground coal mines, complicated geo-conditions, and intelligent coal mining are relevant. Interdisciplinary topics across material research, applied sciences, and mining engineering with a focus on polymer modification and practical technologies for coal mines with different geological conditions are especially welcome. The topics of polymer materials and technologies used in underground coal mines are relevant, and these include but are not limited to:
- Review of the application of polymers in underground coal mines;
- Polymer modification and equipment improvement;
- Effects of geological conditions on polymer materials;
- Polymers and technologies for deep coal mining;
- Polymers and technologies related to disaster prevention;
- Polymers that improve automatic and intelligent coal mining.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
