Abstract:	Chapter 1: Introduction to Hot Water Drilling 1-1 Chapter 1 CHAPTER 1 1: INTRODUCTION TO HOT WATER DRILLING 1.1 Introduction: Hot water drilling is used in situations where access holes in ice are required in very quick time. Due to the fact that a given volume of ice will result in a smaller volume of water when it is melted (as shown in Figure 1.1), the volume of water pumped back out of the hole can only be about 90% of the water deposited. Over time this causes the surrounding ice to melt and results in a reservoir of water. The heaters are scaled to provide the required water temperature rise at the required flow rate. If this drill head is a larger diameter th...
