The mining industry is often faced with great difficulty in drilling deeper and deeper holes in the search for oil and gas. This results in constantly increasing costs and the continuing need to create better materials and technologies to reduce possible losses. Drilling technology must cope with high temperatures and pressures in the hole and other unfriendly environmental conditions. Increasing demands on the properties of the slurry and cement stone force the search for unconventional solutions and materials th...

In this study, the geomechanical properties of the heterogeneous limestone rocks in ??rnak coal mine roof cemented at cracks and the effect of the qualities of cementing paste fill on strengthening by the different silica fume paste were investigated. For this purpose, uniaxial compressive strength, point load strength, impact resistance, friction with Abrasion Loss, Impact Abrasion Loss (Los Angeles Assay) tests were managed following the cemented 50x50x50mm blocks. Even the physical properties; density, water ab...
