To dream of being in a quarry and seeing the workmen busy denotes that you will advance by hard labor.
An idle quarry signifies failure, disappointment, and often death.
To dream of a quarry means you will have to put in some very hard work to advance on your present job. If no one is working in the quarry then this shows that you will entertain disappointment and failure in your present job. Opening up an old, long unused quarry denotes that you will be successful after adversity.
If you dream of working in a quarry, getting out pieces of rock, you will have to work hard for a meager living.
