With　social　and　economic　development　and　improvement　of　science　and　technology,　tunnel　boring　machines,　raise　boring　machines,　reaming　machines　and　road　headers　have　been　unprecedentedly　applied　to　underground　engineering　construction.　Mechanical　rock　breakage　experiments　became　an　indispensable　mean　for　mechanical　excavation　of　underground　engineering.　It　can　also　guide　the　design　and　operation　of　excavation　machines.　This　paper　introduces　the　new　mechanical　rock　breakage　experimental　platform　developed　by　Beijing　University　of　Technology.　The　design　and　manufacture　of　this　platform　considered　the　influence　of　high　in　situ　stress,　cutter　head　rotation　and　rock　breakage　by　multi-cutters　at　the　same　time　on　the　rock　breakage　process.　Different　tools,　such　as　rolling　cutters,　scraper,　ripper,　and　pick,　for　different　excavation　machines　can　be　tested　in　the　platform.　It　can　also　take　into　account　the　different　rock　mass　structure　in　the　sample　box.　Different　construction　conditions　with　different　cutting　tools　can　be　realistically　modeled.　The　experimental　platform　consists　of　a　mechanical　system,　a　hydraulic　system,　an　automatic　control　system　and　a　data　acquisition　system.　After　installation　of　the　designed　experimental　platform,　several　tests　with　different　construction　conditions　were　conducted.　The　experimental　results　showed　that　the　platform　reached　its　design　requirements.　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
