Fel rhan o'n rhaglen o dreialon technoleg, mae offer synhwyro a thechnegau arsylwi ar y ddaear wedi'u cyflogi mewn dros 70 o safleoedd tomenni glo risg uwch ledled Cymru. Mae technegau pellach yn cael eu hystyried i'w gweithredu ar safleoedd dethol cyn y gaeaf sydd i ddod, gan edrych ar systemau synhwyro o bell a monitro telemetrig amser real ychwanegol.
As part of our programme of technology trials, sensor equipment and earth observation techniques have been employed at over 70 higher-risk coal tip sites across Wales. Further techniques are being considered for implementation on selected sites before the upcoming winter, looking at additional remote sensing and real-time telemetric monitoring systems.
