#Sinkhole's will unexpectedly appear though thankfully they are very rare arising in connection with #cellars, #drains, #tunnels, #wells, #sandcaves, #mineworking and the #dissolution of #limestone, #chalk, #gypsum and salt. Any idea what this hole was caused by? @AubournFarm.
Bit of a brown trouser moment today when a sink hole developed on the headland in the beet field we were lifting. Harvester and trailers had been over the area several times already then one of the tractors just suddenly began to drop out of site๐ฎ

#Siteinvestigation in #Bristol today. Follow on #Coal #Mine #Risk #Assessment #microdrilling survey to assess the risk of #mine #shaft proximity hazard and shallow #mineworking. Well done #Geoteam for finding old roadway at 15m depth.
Todays #microdrilling #siteinvestigation found very #shallow #coal #mineworking (recovered as 2m broken ground) only 3.5m below this surface. Whereas we're reccommending removal by surface machine dig this option would not have been viable with picks & spades 200 years ago.
#Geoinvestigate's expert #coal #mining #risk #assessment #CMRA team tackle a complex former #colliery site. 24 #mineentries all #mineshafts up to 400m deep and mostly untreated. #Shallow #mineworking also present. #Siteinvestigation to follow to refine 'zones of influence'.

#Geoinvestigate continue to lobby #Coal #Authority and #HSE to tighten up on breaches of #coal and #mineworking #drill permit conditions by some dodgy #siteinvestigation firms.
Very interesting #siteinvestigation in #Berwick #Northumberland today for major #housing project. #Drilling encounters very shallow #mineworking while site scrape finds unexpected #mine #shaft. Expecting great pics when suspected #horse #gin platform is uncovered next week.
Great 2 days in #Bristol for #Geoinvestigate's experts carrying out #CMRA #coal #mining #risk #assessment follow on #coal and #mineworking #siteinvestigation #drilling and #rotary #probing. Phase 2 #foundation #design #groundinvestigation to follow.
#Geoinvestigate #CMRA #coalmining #risk #assessment identifies unnatural appearing rectilinear pattern and ground sagging on Lidar map probably indicative of very shallow (<10m) historical #coal #mineworking #subsidence near #Durham. #Microdrilling #siteinvestigation to follow.
#Geoinvestigate's #SINKHOLE & #MINESHAFT #HELPLINE assists caller from #Dudley with recurring ground sinkage problem following heavy rainfall. Historical maps suggest feature likely to be a well & not a #mineshaft or #mineworking. #Drilling #siteinvestigation may provide answers.
