There are- several in-seam coal research projects currently under investigation by the Cooperative Research Centre for
Mining Technology and Equipment (CMTE). The overall aim of the projects is to produce new technologies to enhance
safety and the efficiency of in-seam gas drainage drilling. Results from high pressure waterjet rotary drilling trials indicate
that by applying high pressure water to a rotary drill bit, the hole can be drilled to follow the planned trajectory very
closely. Steerable drill bits for drilling long holes (>1 km) have been produced and trialed. A flexible high speed drilling
system provides a capacity for rapid in-seam drilling, particularly suited to cross panel drainage. Geophysical tools are
being developed to provide a geological steering capability and a better understanding of potential gas outbursts zones.
