At the beginning of our study, i.e.. before opening the Bełchatów brown coal mine and the power station 155 species of lichens were registered in the period 1970-1985. A preliminary estimation of the influence of the Bełchatów Industrial Region (BIR) on the lichen flora has been performed. More than 1% of the lichen flora has entirely disappcared, about 43% of the species have shown partial devastation of their localities and numerous localities of more than 35% of taxa have been threatened.

181 taxa of lichenized <i>Ascomycotina</i> (including four species of lichcnicolous fungi) occurring in the Bełchatów Industrial Region (BIR) are described. They present the original state of lichen taxonomic diversity and their resources. before the strip brown coal mine and electric power station of BIR were put into operation.

Abstract Induced seismicity is an increase in seismic activity caused by the human engineering. An example of such activity is the mineral exploration, large water reservoirs construction, exploitation of underground oil and gas storages, etc. The authors studied the seismicity in the Uglegorsky district of Sakhalin region, where the Solntsevskoye brown coal field is located, which is the most promising in the island. Its area is over 100 sq. km, and productive strata of the Verkhneduiskaya formation with a thickness of up to 600 m contains 12 coal seams, 8 of which are working. Active mining of brown coal is carried out at the Solntsevsky coal mine, and blasting operations are performed on a large scale, that, as a result, does not exclude the relation of the seismic process to technogenic seismicity. The earthquake recurrence curves for two decades beginning from 2000 to the present were constructed in the work to compare the characteristics of the seismic regime in the studied area. The difference in the slope angle of recurrence graph during the period of 2011-2020 (the period of the most active development of the Solntsevsky coal mine) from the previous decade is quite significant. The maps of spatiotemporal distribution of seismic events epicenters in the vicinity of Solntsevsky coal mine are constructed. The contraction of zones of seismic events concentration to the mining areas, first of all to the Solntsevsky coal mine, have been found. Such a combination allows us to talk about an increase in seismicity of the region during the last years and change in its character from the natural to a mixed natural and technogenic. The focal mechanisms of the largest earthquakes occurred in the Uglegorsky district have been constructed in order to prove the change in seismicity character and reasons for the earthquake occurrence in the studied area. The mechanisms of seismic events of 2020 are classified as strike-slip faults, that is not character for the most earthquakes on the territory of Sakhalin Island. The authors made an attempt to determine the regularities of the parameters of the produced blasts and earthquakes through dynamic parameters of the seismic events foci by means of studying the frequency content of earthquakes and blasts in order to determine a corner frequency from the focal velocity spectrum.

The article dwells on the topic of competition between coal and solar energy as types of fuel. The authors provide a comparison of the installed capacity of a virtual solar power station and an existing coal power station located within the land allotment of a coal mine. The development prospects of the coal industry in terms of thermal coal are shown.

&lt;p&gt;Satellite radar interferometry, in particular time series techniques, allow to monitor the activity of the surface of vast areas, making them a complement and alternative to traditional geodetic methods, the use of which in such areas is often associated with significant restrictions. The above-mentioned areas definitely include open-cast mines, among others the analyzed Be&amp;#322;chat&amp;#243;w Brown Coal Mine (Poland).&lt;br&gt;During the studies, 216 satellite images acquired from the Sentinel-1A and Sentinel-1B satellites (path 175) for the period from October 17, 2014 to June 11, 2019 were used. Due to the fact that the research area was on two adjacent stages, it was necessary to combine data for the correct performance of the calculation process. The use of the SBInSAR imaging processing algorithm allowed to generate 839 interferograms carrying information about the difference in interferometric phases between pairs of images which satisfy the condition of the boundary size of the spatial and temporal base. As a consequence, it allowed to determine the displacements in the direction of the electromagnetic beam LOS (Line of Sight) that occurred in the mining area during this period.&lt;br&gt;Based on the carried out calculations, significant activity of the area around the open-pit mine was perceived. Dumping ground were analyzed - external Szczerc&amp;#243;w Fields and internal Be&amp;#322;chat&amp;#243;w Fields, as well as excavations where mineral extraction is currently taking place. Continuous deformations (depressions and uplifts) associated with intensively conducted mining exploitation and complicated geological and mining conditions occurring in this area were observed (arrangement of rock layers, faults, the D&amp;#281;bina salt debris separating the Be&amp;#322;chat&amp;#243;w Field from the Szczerc&amp;#243;w Field).&lt;/p&gt;

<p>The nexus between environmental bio-remediation and environmental design, as it pertains to disused coal mining sites in Australia, is little investigated. Increasingly, many of these open cut extraction holes around south-eastern Australia, are becoming redundant as their resources are exhausted or non-economic viability creeps into the industry or are becoming management ‘nightmares’. The recently announced March 2017 cessation of the Yallourn Power Station and associated brown coal Open Cut, and the recent fires and insurance liability legal determinations of the Yallourn Open Cut are exemplar of the former and latter respectively.</p>This paper surveys the deeper bio-remediation and ecological transformative issues directly associated with the Anglesea brown coal Open Cut, and offers an ecological design lens insight as to possible treatments and scenarios that can be offered to guide the future use and management of the site. The lens demonstrates the richness that interdisciplinary design and applied research offers in assisting the healing and mediation of sites. The extraordinary nature and scope of the Anglesea coal mine site provides an opportunity to create a range of cultural attractions, natural succession treatments, natural bio-remediation strategies and educational opportunities. One scenario, for an Anglesea Lake Eco-Resort, proposes to incorporate an integrated Aboriginal cultural destination, performance centre, art installations and recreational venues, engaging the Anglesea community, visitors, researchers and students towards creating a vibrant and unique environment.
