Clear lag without joining world

[hexnet 0]

Hello everyone,

So i am currently playing a custom modpack with a friend, and we are mining cobblestone with a buildcraft quarry. Now the chest we are feeding the cobblestone into is full and we have a bunch of cobblestone laying on the ground. It is so much cobblestone that the server we are playing on immediately crashes when the chunk is loaded. I have downloaded the world and tried to play it in singleplayer. When joining the world it loaded for about a minute or so, then i could see a part of the world and a bunch of cobblestone on the ground, then the game crashed.

Is there any way to get rid of all that cobblestone without joining the world?

We are playing on forge 1.12.2.

Sorry for my bad english, thank you
