“…Therefore, it can be interpreted that the lack of a clear acceleration-like process in the dataset indicates that the nucleation process of the high-energy events did not start in the area of the longwall panel but beside it. May be the strongest event in the catalogue is rather triggered than induced (Mendecki et al 2020). Oppositely, the transition, which has the accelerating-like behaviour, could show that it was caused by the mining through stress release, which in turn induced seismicity correlated to the previous longwall panels.…”

The influence of distant coal seam edges on seismic hazard during longwall mining

2020

Underground coal seam mining has been carried out in the Upper Silesian Coal Basin, Poland, for many years and with a simultaneous increase in exploitation depth. Frequently, coal seams are not fully extracted due to numerous reasons which lead to their edges and remnants remaining in the rock mass. Even in the case of the full extraction of a coal seam, mining usually ends at the border of a protecting pillar to protect underground or surface objects, sometimes at the border of the mining area, or some distance from the old goaf or high throw fault. Extraction of subsequent coal seams in an analogous range results in a cluster of coal seam edges remaining. In the vicinity of the mentioned remainders, the disrupted stress distribution is expected. The infraction of the aforementioned equilibrium repeatedly results in the occurrence of strong mining tremors. The observations from the studied coal seam no. 408’s longwall panel indicated that mining works are able to disturb the present stress-strain equilibrium in the area of the edges of other coal seams, even if they are located at a greater vertical distance away. The seismological parameters and distributions have been applied for this purpose.

“…These activities that cause perturbation to the underground system can alter the pressure and stresses in the nearby dormant faults. Various case studies have attempted to understand the connection of mining (Mendecki et al., 2020) and fluid production with induced seismicity (Benson et al., 2020; Davies et al., 2013; Deng et al., 2020; van Thienen‐Visser et al., 2018; Zbinden et al., 2017). Meanwhile, researchers have agreed on the effect of waste fluid disposal (Healy et al., 1968), geothermal systems (Bommer et al., 2006), oil and gas production (Chang & Segall, 2016; Suckale, 2009; Villa & Singh, 2020), and hydraulic fracturing (HF) (Bao & Eaton, 2016; Brudzinski & Kozłowska, 2019; Deng et al., 2016) on the activation of dormant faults, especially that the time of some of these operations was linked to the seismic events occurring in the respective region.…”

Analysis of the Hydrogeological Conditions Affecting Fault Response to Nearby Hydraulic Fracturing

The response of critically stressed dormant faults to fluid perturbation, by oil and gas production, has been a major public concern because of its link to induced seismicity. In this paper, we study the hydrogeological factors that affect a nearby fault response, during and after hydraulic fracturing (HF) operations, evaluated by the change in Coulomb Failure Stress (CFS) and the rate of seismicity (R) through coupling solid deformation and fluid flow. Our results show that the pore pressure increases rapidly in a fault that is close (hydraulically connected) to HF operations, which might lead to its activation when the injection rate is high. When the fault is adjacent to HF but distant from it, its shallow region is subjected to a stabilizing deformation‐induced normal compressive stress and its deeper region is destabilized under extension. In this case, the fault orientation and damage zone size have a significant effect on the fault's stability and response. On the other hand, decreasing the rate of injection can either increase or decrease the CFS values depending on the fault location and the dominant stresses. Therefore, serious attention should be given to the fault position, its architecture, and the injection rate to help reduce the potential for induced seismicity from HF. Our findings are verified and confirmed using the case of the Duvernay formation in Alberta, Canada, where the reported seismic data correlate with high CFS and R values.
