The initiation sequence is then determined on the surface with the aid of the delays in the surface connector units. The long delay time of the in-hole detonator as compared to that of the surface connector, enables all blast holes to be activated before any rock displacement begins, thus eliminating the risk of misfire.<\/p>\n<p>Another great advantage of the Nonel tunnel system is that the explosive column is initiated effectively from the bottom. The shock wave is enclosed inside the Nonel-tube thus not causing axial initiation of the column charge. This gives full exploitation of the explosive energy and minimizes flyrocks. Vibrations and airborne waves are significantly reduced and better rock fragmentation is achieved.<\/p>\n<p>The Nonel system can be used to all surface, smooth-blasting, pre-splitting and trench blasting operations. For tunnels and underground blasts, Nonel tunnel should be used.<\/p>\n<h4>Packaging<\/h4>\n<p>meet the varying demands on initiation system delay times for different kinds of blasting operations, there are 4 different basic delays for the in-hole detonators and 6 different delays for the surface connector units.<\/p>\n<table>\n<tbody>\n<tr>\n<td class=\"tbl-header\" colspan=\"2\"><strong>Detonel In-hole detonators<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>Designation<\/strong><\/td>\n<td><strong>Delay time (ms)<\/strong><\/td>\n<\/tr>\n<tr>\n<td>DH 425<\/td>\n<td>425<\/td>\n<\/tr>\n<tr>\n<td>DH 450<\/td>\n<td>450<\/td>\n<\/tr>\n<tr>\n<td>DH 475<\/td>\n<td>475<\/td>\n<\/tr>\n<tr>\n<td>DH 500<\/td>\n<td>500<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<table>\n<tbody>\n<tr>\n<td class=\"tbl-header\" colspan=\"3\"><strong>Detonel Surface connector units<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>Designation<\/strong><\/td>\n<td><strong>Delay time (ms)<\/strong><\/td>\n<td><strong>Colour<\/strong><\/td>\n<\/tr>\n<tr>\n<td>DS0<\/td>\n<td>2<\/td>\n<td>Green<\/td>\n<\/tr>\n<tr>\n<td>DS17<\/td>\n<td>17<\/td>\n<td>Yellow<\/td>\n<\/tr>\n<tr>\n<td>DS25<\/td>\n<td>25<\/td>\n<td>Red<\/td>\n<\/tr>\n<tr>\n<td>DS42<\/td>\n<td>42<\/td>\n<td>White<\/td>\n<\/tr>\n<tr>\n<td>DS67<\/td>\n<td>67<\/td>\n<td>Blue<\/td>\n<\/tr>\n<tr>\n<td>DS109<\/td>\n<td>109<\/td>\n<td>Black<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<table>\n<tbody>\n<tr>\n<td class=\"tbl-header\" colspan=\"3\"><strong>In-hole detonators DH400-DH500<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>tube length (m)<\/strong><\/td>\n<td colspan=\"2\"><strong>packing 1.4 \u0392 Qty\/box<\/strong><\/td>\n<\/tr>\n<tr>\n<td>4.8<\/td>\n<td colspan=\"2\">100<\/td>\n<\/tr>\n<tr>\n<td>7.8<\/td>\n<td colspan=\"2\">80<\/td>\n<\/tr>\n<tr>\n<td>10.2<\/td>\n<td colspan=\"2\">60<\/td>\n<\/tr>\n<tr>\n<td>12.0<\/td>\n<td colspan=\"2\">50<\/td>\n<\/tr>\n<tr>\n<td>15.0<\/td>\n<td colspan=\"2\">40<\/td>\n<\/tr>\n<tr>\n<td>18.0<\/td>\n<td colspan=\"2\">35<\/td>\n<\/tr>\n<tr>\n<td>21.0<\/td>\n<td colspan=\"2\">25<\/td>\n<\/tr>\n<tr>\n<td>24.0<\/td>\n<td colspan=\"2\">25<\/td>\n<\/tr>\n<tr>\n<td>27.0<\/td>\n<td colspan=\"2\">20<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><strong>Surface connector DS0-DS109<\/strong><\/p>\n<table>\n<tbody>\n<tr>\n<td colspan=\"2\"><strong>tube length(m)<\/strong><\/td>\n<td><strong>packing Qty\/box<\/strong><\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\">3.6<\/td>\n<td>100<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\">4.8<\/td>\n<td>90<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\">6.0<\/td>\n<td>80<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\">7.8<\/td>\n<td>70<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\">10.2<\/td>\n<td>50<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h4>Storage<\/h4>\n<p>Nonel detonators should be handled, stored and used according to the national laws and regulations.
