DETERMINATION OF OPTIMAL BLOCK LENGTH ALONG THE STRIKE TO PROVIDE SAFETY AND EFFICIENCY WHEN EXTRACTING MEDIUM-THICK IN-CLINED COAL SEAMS USING ROOM-AND-PILLAR METHOD IN QUANG NINH COAL BASIN

An analysis of appropriateness of room-and-pillar method for extracting handheld-machines medium-thick inclined coal seams in Quang Ninh Coal Basin taking into account existing mining and geological conditions was carried out.Corresponding foreign experience of applying room-and-pillar method was considered in relation to CLARIFYING SHAMPOO the min

Amidst the unprecedented health crisis, annihilation of economy and social security, and upsurge in the loss of job opportunities caused by Covid-19, the emergence of a dynamic global spirit of collaboration has reinvigorated the human ability to work together to respond collectively to any Gazebo Tops peril that threatens the integral well-being o

The wide-swath mode of synthetic aperture radar (SAR) is a good way of detecting typhoon/hurricane winds with a cross-polarization mode.However, its ability to detect wind waves is restricted because of its spatial resolution and nonlinear imaging mechanisms.In this study, we use the SAR-retrieved wind speed, Sentinel-1 SAR wave Wine Coolers mode a
