Hello! You can click the resource patches on the ground to mine from them manually. After getting some coal, open your inventory and place the Drill you have there on a resource patch, click the Drill and insert coal into it by clicking the Coal icon in your inventory. Now the Drill should be mining. Next, place the Storehouse close to the Drill and while the "Build" button is still active, drag from the Drill to the Storehouse to create a Route from the Drill to the Storehouse. Let me know if you need more hints! Good luck :)
