. The spatial complexity of oil shale systems is manifested by microstructure, pore space randomness and extensive heterogeneity. A microwave pyrolysis device developed for this study was used to pyrolyze oil shale, and the microstructure before and after pyrolysis was visually examined and quantified. The internal structure of the rock and the extent of pore and fracture expansion are more accurately determined in this way. The microstructure of oil shale at different temperatures before and after microwave pyrolysis is identified by X-ray microcomputed tomography (μCT) with automatic ultra-high-resolution scanning electron microscopy (SEM), to observe the heterogeneous state of oil shale on 2D and 3D scales and define the distribution of internal pores and fractures by post-processing μCT visualization. The study found that fractures sized from microns to millimeters along with pore fractures were observed at increasing microwave temperatures. The fractures gradually expanded with increasing temperature in the direction of horizontal or vertical laminae and generated a more connected pore network. The kerogen gradually decreased with a rise in temperature. The porosity increased from 0.26% to 13.69% at the initial temperature. This research is essential for the qualitative as well as quantitative analysis of the internal structure of oil shales under microwave radiation.

. This work analyses issues associated with the deteriorated blasting efficiency by the use of emulsion explosives in underground oil shale mines that utilise room and pillar mining methods. The problems were connected with the reduction in entry advance, shattering of pillar walls and falling of the roof. The aim of this study is to improve blasting efficiency that can guarantee a sufficient entry advance and secure stable conditions of the pillars and the immediate roof. The improved blasting pattern was successfully tested under in-situ conditions. It was demonstrated that the entry advance and the stability of the immediate roof and pillar walls were significantly enhanced as a result.
