Narrative:

The aircraft was issued the instructions to taxi to 17L via left and ed; hold short of the 17R approach on ed. Pilot read back correctly the hold short instructions. The pilot then blew past the hold short line causing a go around on short final. The very next week I had the same situation working local control 2 (LC2) and I had to send an aircraft around on very short final with an aircraft in the protection area who had also read back the hold short instructions. I will fill out additional reports for this occurrence as well. This continues to be a problem at den tower. The pilots are confused on where to hold short. When we taxi them north on left or M there are 17R approach signs and lines to hold short. This however is not where we expect them to hold short. So half of them stop on M or left; but we really want them to make the turn on ed and then there is another 17R approach sign there. This is an extremely hot spot when we have arrivals to 17R. They are not crossing a runway; but if they cross the approach sign we are required to send the aircraft around on short final. I believe in the 7 years I have been here I have sent over 10 aircraft around on short final because of this problem. Times that by 40 controllers and we have a pretty big issue here. So to make it clear we issue; 'runway 17L taxi via (left or M); ed hold short runway 17R approach.' on either taxi route there are 2 17R approach lines to hold short of causing confusion.there should be one line depicting where we want the pilot to hold short of; and this should stick out to the pilot and no be something of question. If you need to paint a purple line or hot pink line and have a different name for it; that may work. The pilots don't understand what we are asking them to do. I have filled out 2 pilot deviations this week because of it.

Title: DEN Tower Controller reports of a problem with aircraft not holding short of an approach area to a runway causing aircraft on short final to go-around.
